A former milkman who sexually abused two young boys after grooming them with gifts and money was yesterday jailed for five years and placed on the sex offenders' register for life.

Norwich Crown Court heard that Trevor Mallett, 62, also showed the boys porn and plied one of them with alcohol before going on to sexually assault them. He also filmed one of the boys he assaulted.

The court heard the offences date back nearly 20 years but only recently came to light after one of the victims came forward to make a complaint. The offences are said to have had a "devastating and lasting effect" on the two victims.

Mallett, of Hemming Way, Norwich, admitted indecent assault on the two boys when they were aged about 14 to 15. Jailing him Judge Daniel Worsley told him he had carefully groomed his first victim giving him gifts and money.

"You cunningly groomed him, worming your way into a position where you could sexually abuse him and gratify your abnormal desires."

He said he had later started on his second victim - "this time on several occasions he plied him with alcohol in quantity". He said the offences had had a devastating and lasting effect on the victims. However he accepted that the offences happened some time ago and he had not reoffended but said: "The victims have lived with the misery of the knowledge of what happened to them."

Nick Cotter, prosecuting, said Mallett had given the first victim money and gifts including a Sony Walkman. He said the victim recalled how Mallett's behaviour had "made him squirm and feel sick" but he had been coaxed by the gifts and money Mallett had given him.

Mr Cotter said the second victim had been plied with Gold Label beer which made him feel confused and ill and then Mallett had gone on to assault him.

He said the victim remembered using the alcohol to cope with what was happening.

Mallett was arrested after the second victim came forward years later to make a complaint as he was suffering from profound problems because of what had gone on when he was a teenager.

Ian James, mitigating, said: "He fully acknowledges he has committed a very serious wrong in relation to the two boys."

He said Mallett was full of remorse and added: "He has now put this sort of behaviour behind him."

Mr James said any time in jail would be particularly difficult for Mallett. "Offenders of this kind do not have a nice time inside."
