A FORMER special police constable who made sickening videos of himself raping and indecently assaulting young girls was jailed for ten years last week.

Student teacher Dominic Patrick McCallan, 28, from Medomsley, gained the trust of parents by teaching their children judo, Newcastle Crown Court was told.

And police say they fear many more girls may have fallen victim to the evil paedophile, without even realising they had become his prey.

At last Friday's hearing, Judge David Hodson took the unusual step of allowing a video made by McCallan to be shown to the court.

Court staff, barristers and journalists sat in stunned silence as the crimes were shown, while McCallan hung his head and cried.

The video showed several indecent assaults and a rape on three girls aged about ten during a bogus first aid test.

One of the girls filmed being abused while she slept, did not know of the crime to this day, the court was told.

Prosecutor Beatrice Bolton said the attacks took place between 1995 and 1999. She told the court that McCallan was a special constable with the Durham Constabulary for six years until 1997.

He then started an education degree at Sunderland University with a view to becoming a primary school teacher specialising in IT.

When police raided McCallan's home, they found 8,000 indecent pictures in his computer taken from 209 pornographic internet web sites. During a six month investigation police interviewed more than 200 children.

At a previous hearing, McCallan pleaded guilty to one charge of rape, four charges of indecent assault, three of taking indecent photographs, and six of possessing indecent pictures of children.

Sentencing him to 15 years - ten years in custody with a five-year supervision order on his release - the judge said: "I do not think it is an exaggeration to say this is one of the most disturbing cases I have come across in all my years on the bench.

"By deceit and deception you engineered a situation whereby young girls and their parents were tricked into believing you were a responsible person who could give judo instruction to their children."

The judge added: "You are an exceptionally high risk to young girls. The effect on those children must be profound. No one can tell what long term damage you have caused them."

He ordered that McCallan should be placed on the sex offenders' register indefinitely.

Gail Hopper, one of Durham County Council's social services managers, said: "We have taken a dangerous man off the streets, who no doubt would have gone on to abuse more children."

Det Insp Neil Redhead said he believed the investigation team had even identified the little girl who was to have been his next victim.
