A teacher has been convicted of abusing a teenage boy in the late 1980s.

David Gutteridge, 60, of no fixed abode, was found guilty of two counts of indecent assault at a retrial at Harrow Crown Court on Tuesday. He will be sentenced on March 13.

Gutteridge was a teacher at Orley Farm Preparatory School in South Hill Avenue, Harrow in the 1980s.

The victim was aged between 14 and 16 at the time of the assaults.

Between 1986 and 1988, Gutteridge, who was a family friend, would invite the victim to his flat at weekends and ply him with cigarettes and alcohol. He would then ask the victim to watch pornographic videos, before abusing him.

The abuse came to light when the victim, now in his late thirties, confided in his wife about the abuse he had suffered as a boy. The victim subsequently went to the police.

Gutteridge was arrested at his home address in Kent in September 2013and subsequently charged with indecent assault on a boy under the age of 16.

The first trial took place last September and ended in a hung jury. The retrial started on February 1.

Detective Constable Claire Harrison of the Metropolitan Police's Sexual Offences, Exploitation and Child Abuse Command, said: “The victim has stated that the abuse has had a significant detrimental effect on his life due to what happened to him in his formative years.

"I would like to pay tribute to his courage and strength in coming forward and standing up in court to tell his story."
