A grandfather picked up two truanting schoolgirls before giving them vodka and sexually abusing them, a jury heard today.

One of the girls told Oxford Crown Court she screamed as Carl Forrester, 55, attacked her on the sofa after driving her and a group of friends to his house.

Forrester, of Canning Crescent, South Oxford, denies two charges of sexual activity with a child, four of taking indecent images of children and two of making indecent images of children.

The girl, who cannot be named but was 12 at the time of the alleged attack in July 2007, said: “He came and sat next to me and started to try to touch me up. I felt sick. I tried pushing his arm off me but he had too much strength. I was screaming.”

Peter Coombe, prosecuting, said the girls were playing truant when the defendant picked them up in his car and gave them alcohol.

He said two of the girls, the 12-year-old and another then aged 13, told police he sexually abused them.

He added police searched Forrester’s home and found more than 300 indecent images of children on two computers and a disk.

Mr Coombe said: “The defendant clearly had, the prosecution say, an interest in underage girls.

“It is an extraordinary coincidence that (the girl) describes the sort of sexual abuse that she does at the hands of the defendant and then found on the defendant’s computer are a vast number of images which show exactly that propensity and interest and taste.”

The case continues.
