A MAN who raped and sexually assaulted two young girls in the 1970s, one for almost a decade, was jailed for 10 years today (Friday).

Derek Frost, of Southbourne Gardens, Ruislip, was found guilty of 10 charges: five indecent assaults and three rapes - including rape on a girl aged just 11 years-old - as well as two serious sexual assaults.

Frost, 58, denied the allegations, but a unanimous decision by the jury at Isleworth Crown Court found him guilty of all charges.

The court heard that he sexually abused his two victims between 1971 and 1980.

Several took place at addresses around Ruislip and Eastcote, including Ruislip Woods, and near to the River Pinn by Eastcote Cricket Club in High Road.

Frost was 15 when he started his offending. The first victim, now in her 50s, was just 11 when her abuse began, and it continued throughout her teenage years until she was 19.

The second victim was aged 14 and 15 when she was raped, including one occasion where she was attacked in her school uniform.

Giving evidence, the first victim told jurors that after the first attack, Frost told her if she spoke to anyone about the abuse, she would be dead.

“I thought, as long as I went along with it, as long as I didn’t tell anyone, I would be alive. I felt it was wrong, but I was too young to even know what it was.

“Before it started I thought you could only get pregnant if you were married, and I thought babies were born from your belly button. I knew nothing about sex.

“I haven't told nobody about this for so long. I didn’t want anyone to know, but now I have told it, I want it all out in the open," she said.

Judge Robin Johnson sentenced Frost to 10 years behind bars, and ordered his name to appear on the sex offenders register for life.
