A gang of moped 'scumbags' exposed by BGT judge Amanda Holden for threatening to snatch a toddler have been jailed for a total of 68 years today.

The 12-strong mob carried out a series of high-profile raids around the capital - even trying to steal TV cameras from bridges on the university boat race route - before making off on mopeds.

Ms Holden got involved after four gang members were caught on CCTV targeting her neighbour, Pheobe Ruele, as she walked her little son home from nursery last summer.

Bearded gang ringleader Terry Marsh, along with Steven Weller, John McFadyen and his brother Isaac, tried to rob Miss Reule in the middle of the road, demanding 'give me your rings or I'm going to hurt your child'.

They were spotted by a group of builders who chased them off brandishing scaffold poles.

The gang were finally rounded up following another raid, after a 90-minutes chase through 10 London boroughs, which ended when one pair slid off their bike while trying to take a corner at high speed.

Helicopter footage shows the moment three of the gang slid off their moped after a chase which had lasted more than 90 minutes and spanned 10 London boroughs, with all three piled onto the same bike. At one point they even drove the wrong way up the A40 into oncoming traffic to try to shake off the helicopter, police motorbikes and dog units chasing them

They were chased into a graveyard when one was detained. Officers discovered a hammer, screwdriver, angle grinder and large knife underneath the seat cover of one of the mopeds

Footage of the attack in Richmond, south west London, was tweeted by the Britain's Got Talent judge who urged the public to call the police 'if u know these scumbags' after it happened last June

All four were jailed at Kingston Crown Court today, along with six other members of the 12-strong gang who were also responsible for a string of high profile raids across London. Two were spared jail.

The gang were behind the theft of £170,000 of camera equipment used to film the Oxford and Cambridge boat race.

Nine of the 12 had racked up 383 previous convictions for burglaries, handling stolen goods, car theft, aggravated vehicle taking, assault and robberies between them. The other three men had no previous criminal records.

Speaking exclusively to MailOnline after the gang were convicted last week, Amanda Holden said: 'I'm delighted these criminals have been brought to justice. It's nice to see how social media can work in a positive way when we all work together.'

Today the thugs, aged between 18 and 36, and who were all linked to ringleader Marsh, 32, appeared for 12 offences, including conspiracy to rob, conspiracy to burgle, conspiracy to steal, criminal damage and handling stolen goods.

Judge Georgina Kent told the 12-strong gang, who were crowded into the dock at Kingston Crown Court: 'Many offences were committed using motorbikes or mopeds, often stolen with false number plates. Many offences were committed at night.'

Judge Georgina Kent sentenced them, saying: 'All 12 of you have been involved in conspiracies to steal, burgle and rob as well as other offences.

'Between you you have caused a great deal of harm, loss and damage to a large number of victims.

'Apart from the financial cost, there's the human cost in anxiety, distress and fear caused to the victims and to those who witnessed and heard about the offences. Your offending has cost a great deal in police resources.

'These were very professional planned and organised offences. The common denominator is Terry Marsh.'

She said there was little forensic or physical evidence to the crimes which were mostly carried out at night and added: 'Terry Marsh was supremely organised and diligent in rotating SIM cards and phones he used.'

The judge continued: 'At about 12.30pm on 21st June 2018 Mr Marsh, Mr Weller, Isaac McFadyen and John McFadyen attempted to rob a young mother who was with her child.

'This was an extremely serious offence, the robbery was captured on CCTV and reported in the media.

'Apart from the impact on the victim, the nature of offences caused shock and concern to those who heard about it.'

The McFadyen brothers approached the mother Phoebe Reule as she was walking hand in hand with her three-year-old son after picking him up from nursery.

The judge said: 'All four men were dressed in black motorbike clothing and black full face helmets.

'They were waiting for Miss Reule so they must have targeted her when they walked past her. Mr Marsh and Mr Weller moved their bikes into Sandpits Road.

'It's striking that the robbers were so confident that they targeted their victims in full public view.

'When Phoebe Reule and her son arrived at the mouth of Sandpits Road, the McFadyen brothers approached them together. She said she could see Mr Weller and Mr Marsh.

'John McFadyen grabbed hold of Ms Reule by the arm, as he did so John McFadyen demanded her rings and threatened to hurt her child.

'He said, 'give me your rings or I'm going to hurt your child and take him away'. As he said that he bent down as if to move towards the child.'

The judge added: 'Ms Reule was terrified, she instinctively picked up her son and dragged him back towards the road - fortunately there were no cars in the vicinity at the time.

'Miss Reule's instructive reaction caused John McFadyen to release her arm. Ms Reule shouted, 'help help they are trying to take my child'.

'The most serious aggravating feature was the targeting of the victim due to her vulnerability and the nature of the threat made.

'A mother and her three-year-old son are extremely vulnerable. The threats that were made were calculated to exploit that vulnerability.

'To threaten a mother with violence towards a very young child and to threaten to take the child away is a most effective and distressing threat.

'I have no doubt that this offence would have struck fear into any parent who heard about it.'

The gang's illegal activity first came to light on New Year's Eve 2017 after a ram raid on outdoor clothing company Altimus Ltd in Kensington using a stolen Range Rover and several mopeds.
