A female prison officer has joined her murdering lover behind bars after she showered him with gifts including alcohol, drugs, mobile phones - and even porn.

Anita Allenby, 57, became infatuated with 28-year-old Falak Alam, who was put in prison after stabbing a man to death over a bodged drug deal when he was 16.

Mum-of-two Anita then smuggled in three phones, Spice, Subutex, steroids, cannabis, porn and vodka into HMP Full Sutton for Alam during a four-month period.

Hull Crown Court, East Yorks., heard evidence of the bounty was covertly hidden in 60 hand-written 'love letters' to Allenby - after they struck up a 'sexual relationship'.

Alam had requested Anita to bring him pornography on memory sticks which 'goes like hot cakes' - as lags were offering to pay £1,500 for three devices.

Prosecutor Mark McKone said of Allenby, who began working at the jail in 2005: 'She fell in love with Falak Alam, despite being 29 years older than him.

'Falak Alam might or might not have been in love with her, but they had a sexual relationship, as evidenced by the letters.'

Alam used his disabled brother Arif Alam, 31, to source the contraband, which was worth three times its street value in prison, and hand it to Anita to then pass on to the inmate.

The court heard the conspiracy was 'largely successful' - but it was slang terms found in the love letters in December 2014 that were the scheme's undoing.

Alam spoke of having 'decent dark' in reference to cannabis resin, but said the skunk [herbal variety] was 'poor quality'.

He used 'bag of sand' to refer to a 'grand' - ie, £1,000 - and also said 'people going to turn up with the paper' in another reference to cash.

Alam also offered to buy Allenby new laptops and a 'pressie' in return, telling her: 'I'll get someone to get you one from PC World.'

Jailing the trio for a total of 15 years, judge David Tremberg, QC, told her: 'You, Anita Allenby, well knew that the relationship itself, and what was to follow, was fundamentally incompatible with your role as a prison officer.

'To behave as you did was a root and branch abuse of trust and a dereliction of your core duty.'

Allenby, of Howden, East Yorks., admitted conspiracy to supply MDMA, conspiracy to supply cannabis, and conveying mobile phones into prison.

She was jailed for five years and ten months.

Falak Alam admitted conspiracy to supply MDMA, conspiracy to supply cannabis, and conveying mobile phones into prison.

He was jailed for six years and three months, which will start on May 1, 2019, just before his earliest release date.

Arif Allam, of Leeds, West Yorks., admitted conspiracy to supply cannabis, conveying mobile phones into prison, and a range of driving offences after stealing and crashing his disabled father's car.

He was jailed for two years and six months, and was banned from driving for 42 months.

A Prison Service spokesperson said: 'We do not tolerate any corruption and we take swift action against those who undermine the good work of their colleagues or compromise the safety of our prisons.'

'The vast majority of our prison staff are hard-working and honest but the small minority who involve themselves in corruption will face the full force of the law.'
