Cannabis plants worth £1.2m have been seized in a series of drugs raids across Sussex.

More than 1,400 plants were found at 10 properties, sparking seven arrests and the discovery of four potential modern slaves.

Sussex Police said the investigation was triggered by a report of a break-in at a property in Tennyson Road, Crawley, on 2 February.

Police who responded to the call found around 800 cannabis plants and equipment used for their cultivation.

Two men were arrested and interviewed, before warrants were executed at nine other properties.

Modern Slavery in the UK Show all 13 1 /13 Modern Slavery in the UK Modern Slavery in the UK NCA has launched a touring photographic exhibition which aims to portray the signs of slavery and exploitation. Entitled ‘Invisible People’, the exhibition will tour the country as part of the National Crime Agency’s campaign to raise awareness of modern slavery and human trafficking. National Crime Agency Modern Slavery in the UK Child trafficking Child trafficking for sexual exploitation Traffickers use grooming techniques to gain the trust of a child, family or community. The children are recruited, transported and then sold for sex, often returning to their homes immediately afterwards, only to be picked up by the same people again. This is happening here in the UK, to migrant and British-born children. Spot the signs of child trafficking: Often, children won’t be sure which country, city or town they’re in. They may be orphaned or living apart from their family, in unregulated private foster care, or in substandard accommodation. They may possess unaccounted-for money or goods or repeatedly have new, unexplained injuries. National Crime Agency Modern Slavery in the UK Agriculture Some workers in the farming sector, harvesting grains or root vegetables, tending livestock or fruit picking, are being exploited every day in the UK. Victims of this crime in the agricultural sector are often Eastern European men and women, who were promised a job by traffickers, or they could be individuals on the fringes of society, homeless or destitute. Through threats, violence, coercion or forced drug and alcohol dependency, they’re enslaved, working for little or no money, living in squalid conditions having had their identity documents taken from them. Spot the signs of exploitative labour in agriculture: Agricultural slaves often have their wages paid into the same bank account, meaning an illegal gangmaster is likely collecting all their wages. Exploited agriculture workers often don’t have suitable protective equipment, working instead in cheap sports clothing and trainers, and don’t have a different change of clothes from day-to-day. National Crime Agency Modern Slavery in the UK Food processing Polish or Slovakian men are brought to the UK with the offer of employment and, after arrival, gangmasters seize documents, opening multiple bank and utility accounts in their names – but refuse to handover access to the accounts or bank cards. Hours are long and the work is gruelling and dangerous. Workers are abused and are controlled by threats of harm to their families at home. Spot the signs: Those exploited wear inappropriate clothes and often no safety gear – despite working with dangerous and life-threatening equipment. They may often have untreated injuries and be refused medical attention, and will live and work in agricultural outhouses. National Crime Agency Modern Slavery in the UK Construction Labour-intensive sectors like construction, where temporary and irregular work are common, are high-risk sectors for forced labour. With new homes, offices and buildings being constructed or upgraded in great quantity, labour exploitation is the second most common type of modern slavery, after sexual exploitation. Spot the signs of exploitative labour in construction: Exploited workers are often not provided with protective clothing or equipment, and may show signs of abuse or carry old untreated injuries. Slave workers are also likely to work extremely long work hours for six or seven days a week without any leave. Photographer Rory Carnegie, said: “I wanted this image to communicate that despite being forced to live, eat, wash and sleep – where they’re working, in cramped and unhygienic conditions, that there is a human instinct to domesticate. I wanted to show how there is still hope and dignity in the most squalid and difficult of circumstances.” National Crime Agency Modern Slavery in the UK Maritime In the tough maritime industry young men, often Filipino or Indian, Eastern European or African, are promised a better life, but instead find themselves in a cycle of debt and exploitation. Unable to read, they are offered a job, given papers to sign and begin working on a trial-basis, only to be told they have failed and owe money, and have to work more to settle the debt. They may be forced to work for long hours in intense, hazardous and difficult conditions. Photographer Rory Carnegie, said: “In the 80s, Chris Killip published a series of images called In Flagrante, and these images were at the forefront of my mind while composing this shot. I wanted to show the utter desperation of these men - how passed their limit they are. The broken floats and the entire decaying environment around him, I saw as a metaphor for his existence.” Rory Carnegie/National Crime Agency Modern Slavery in the UK Forced prostitution Each year, women from across Eastern Europe and West Africa are lured to the UK by the dream of a better life. Whether by fake migration services or unscrupulous individuals who befriend and then betray them, women fall into a dark spiral of sexual exploitation and forced, unpaid prostitution, unable to escape. Photographer Rory Carnegie, said: “What I really wanted for this image, was to depict how women are used as commodities, the complete control slavery has over them – the helplessness of having to sit and wait for man after man, until no more men arrive. I wanted the image to show how lonely and eventually numbing that experience is, and for that ugliness to be contrasted against the bright blue of the wig – a fancy dress item that we would usually associate with a fun event – but here is used as a disguise, perhaps of her own identity to herself - to further emphasise how unjust the situation is.” NCA Modern Slavery in the UK Cannabis farming The cannabis industry hides a dark secret in the house next door. Gangs bring young boys to the UK from countries like Vietnam and deliver them to a house where, once in, they won’t be able to leave. Forced to tend cannabis plants that fill specially rigged houses, the boys are often locked in and forced to work, sleep and eat in one confined and dirty room. The chemicals used on the cannabis are poisonous, and often victims don’t know where they are or how to get help if they do escape. The eyes, ears and compassion of the local community are essential. Spot the signs: Aside from the strong and prolonged smell of cannabis, have you noticed a house that looks unusual? Are the windows covered or usual entry points blocked? Buildings might be over-heated – in very cold weather is the roof without frost, because the house is being kept warm to grow plants National Crime Agency Modern Slavery in the UK Agriculture Some workers in the farming sector, harvesting grains or root vegetables, tending livestock or fruit picking, are being exploited every day in the UK.

Poor English language skills could indicate exploitation because it suggests someone else must be arranging the work. A brothel is likely to be an average house on a normal looking street, but may have curtains which are usually closed and many different men coming and going frequently. National Crime Agency Modern Slavery in the UK Maritime Spot the signs of exploitative labour in the maritime sector: Victims might appear withdrawn or frightened, often unable to answer questions directed at them or speak for themselves,. They might be afraid of authorities like police, immigration or the tax office, and may perceive themselves to be in debt to someone else. They may not have been given proper protective equipment so can suffer illness or injury. Photographer Rory Carnegie, said: “Throughout the series of images, I wanted to juxtapose the harshness of the lives of slaves against bright primary colours – colours we traditionally associate with happiness or a feeling of wellbeing – to provoke a reaction. The image, as rich as it is, communicates how completely uncomfortable this person is. I wanted to show how his body is not his own, and how he has no right to avoid hardship, avoid the ice, or wear better shoes, he is utterly controlled.” Rory Carnegie/National Crime Agency Modern Slavery in the UK Food processing Photographer Rory Carnegie, said: “This image communicates utter exhaustion and dejection. We can see how dire his situation is. He has no protective gear on, and we can see the extreme tiredness that leads him to a place of anxiety and distraction, where he doesn’t care about whether he’s operating machinery safely, or putting himself at risk.” National Crime Agency Modern Slavery in the UK The exhibition comprises a series of large, freestanding cubes displaying images capturing snapshots of life within different types of modern slavery - in agriculture, construction, maritime, cannabis farming and food processing, child trafficking for sexual exploitation and forced prostitution. Each image comes with written commentary describing what the viewer is seeing, and information about signs which may indicate someone is a victim. National Crime Agency

Detective Inspector Cheryl Lewendon said: “We have completely disrupted a fully planned commercial project which appears to have been operating for several months, and was aimed at bringing illegal drugs on to the streets of Crawley and the surrounding area on a large scale.”

She said the investigation had involved officers across West Sussex and a new tactical enforcement unit, adding: “Our enquiries are continuing to trace other people we suspect of being involved in the organisation and management of these sites.”

On 6 February, 110 plants were found in Cowfold Close, Crawley, and four days later 150 plants were discovered in Three Bridges and another 100 in Worth.

On 12 February, several people allegedly linked to the supply were found inside a property in Woodfield Road, Crawley.

Later that day, 70 more cannabis plants were found in Dobson Road, Crawley.

On Thursday, 120 plants were found at three addresses, one in Alpha Road, and two in Forester Road. Nobody was present.

On Friday, police found 60 plants at two other properties in Crawley.

Six men and a woman, aged between 21 and 38, were arrested on suspicion of cannabis production and released under investigation.

Sussex Police said they were also “referred to immigration enforcement for further enquiries about their status in the UK”.

Two other men, aged 31 and 32, from Stratford in east London, have been interviewed under caution on suspicion of human trafficking offences.

Home Office forced to defend refusal to disclose detention of hundreds of modern slavery victims

Four people found at the sites have been referred to specialist support services as potential victims of modern slavery.

Police have launched an operation codenamed Forfar in an attempt to trace more people in connection with the criminal enterprise and are appealing to the public for information.

The raids came amid continued efforts to battle “county lines” gangs who export drug-dealing operations from cities, such as London, to smaller towns and rural areas.

The trade, which sees children used as drug mules and criminals take over the homes of vulnerable people for their operations, has caused a dramatic rise in British modern slaves.
