A FORMER school lab technician convicted of a sex offence involving a teenage boy has been ordered to do unpaid work after failing to engage with a treatment programme.

Winchester Crown Court was told that because Raymond Winall continued to deny the offence, he had not taken part properly in the sex offenders' treatment.

Revoking the original three-year community order, Judge Andrew Barnett said Winall, 59, would have to carry out 140 hours of unpaid work over the next year. The other parts of his original sentence, imposed in September 2006, remain unchanged.

When he was sentenced last autumn, Winall was placed on the sex offenders' register for five years and disqualified indefinitely from working with children.

During the three-day trial last August, Winchester Crown Court was told that the youth, who cannot be named for legal reasons, had gone to Winall's home in Northbrook, Micheldever, in August 2005 to work in the garden.

In evidence, the boy said that Winall, who was working at The Westgate School at the time of the offence, invited him to watch some videos as a reward for his work. However, the videos were pornographic and, while watching them, Winall encouraged the youngster to commit a sex act. The boy told his parents and Winall was arrested.

At the trial, Winall claimed he had only shown the 15-year-old boy the tapes because he thought that they were educational and because he was worried about a burgeoning relationship the child was having with a girl.

The jury cleared him of actual sexual activity with the boy and of committing a sex act in front of the boy, but they unanimously found that he had deliberately set out to get the boy to perform a sex act on himself.

At the latest hearing last Friday, Judge Barnett warned Winall that any breach of the new order would mean him risking a prison sentence.
