A CHEF who smuggled mobile phones and cannabis into HMP Isis in Thamesmead will get his own taste of life behind bars.

Mick Fray charged prisoner Glen Lawrence up to £300 to smuggle the goods into the prison, with the inmate selling them on at inflated prices to save up for a caravan.

The 46-year-old, of South Norwood, was head chef at Isis when he was approached by the prisoner and agreed to meet the 23-year-old's sister Nikki Nash.

Nash gave Fray mobile phones and cannabis on at least two occasions - in August and September 2011 - which he agreed to deliver to Lawrence for between £200 and £300 each time.

Mobile phones can sell for between £250 and £500 in prison, while cannabis can sell for up to four times its street value, police say. Lawrence wanted enough money for his sister to buy a caravan trailer for him when he got out.

Lawrence, serving time for the robbery of a 15-year-old in 2010, and Nash were assisted by their mother, 46-year-old carer Carolyn Dylan, of Muswell Hill, who helped acquire the contraband and make arrangements with Fray.

When Lawrence called Nash from the prison phone, they used their own derivative of Shelta - a language used by the Irish travelling community - to stop anyone who might have been listening in from uncovering their plot.

At Southwark Crown Court today (June 13) Fray was jailed for four-and-a-half years after being found guilty of conspiracy to supply cannabis, conspiracy to bring a prohibited item into prison, misconduct in public office and without authority causing transmission from within a prison.

Lawrence was given a sentence of four-and-a-half years after his conviction for conspiracy to supply cannabis, conspiracy to convey a prohibited item into prison and without authority causing transmission from within a prison.

Dylan, who was found guilty of conspiracy to supply cannabis and conspiracy to convey a prohibited item into prison, was sentenced to two years in jail.

Nash, aged 25, of Muswell Hill, pleaded guilty to conspiracy to supply cannabis and conspiracy to bring a prohibited item into prison. She was sentenced to 15 months, which was suspended.

Investigating officer Det Con Kevin Gow said: "Fray abused a position of great trust. He had responsibility for supervising up to 30 prisoners at a time in the kitchen and, with the exception of the cells, he had full key-access within the prison.

"What makes his part in the conspiracy even more grave is the fact that when mobile phones are used by prisoners, it is often to help commit crimes such as drug trafficking, witness and victim harassment, and even murder."
