The leader of a Hampstead scout group raped a young boy in a field while on camp and made him pose naked inside the troop’s Savernake Road church hall base, a court heard yesterday.

Ian Barker, of Queen’s Head Street, Islington, is charged with eight counts of child sex abuse between the late 1970s and early 1980s.

The alleged abuse includes taking one boy into a field while on camp and making him pose naked, and on another occasion raping him. He is also accused of making him pose naked in a cupboard during a group meet at All Hallows, in Savernake Road, and of asking another boy to ejaculate into a piece of bread.

Barker, now 56, was in his late teens when the alleged abuse began, and the victims were under 14.

Jurors at Blackfriars Crown Court were played a video of the first victim’s police interview.

In it, he talked about being led into a field by Barker when the other boys were in bed on a camp. He said: “I just couldn’t understand why these actions were anything to do with working towards merit badges.

“He asked me to adopt a particular pose to give him sight of me – leaning over to show him by behind and in another one I was leaning back giving him full sight of my groin area.”

The victim said he remembered telling Barker he was cold and being told to go back to his tent and not speak about what had happened.

But the second time, he said, he was raped. “I remember him putting his hand over my mouth,” he recalled. “And I remember being asked to bend over. I remember him breathing heavily and feeling pain in between my buttocks. It lasted three or four minutes. I remember him withdrawing and I remember being told to pull my pants up and not talk about it again.”

The next morning parents came to pick up their children and prizes were given out for the scouts. The victim said Barker singled him out for a prize.

Jurors heard after he told his parents about some of the abuse, but not the rape, they went to scout leaders – and were assured Barker would not be allowed to work in the organisation again.

The victim also gave evidence in court, from behind a screen, and talked about being in therapy for decades because the abuse meant he struggled with intimacy.

Barker denies three counts of indecent assault, three counts of indecency with a child, buggery and gross indecency.

The trial continues.
