These are the sketches which convinced police officers that a man who became known as Nick may have been telling the truth about a murderous VIP paedophile ring in Westminster.

Carl Beech, 51, is on trial accused of inventing the whole thing and pocketing £22,000 in compensation in the process.

On the opening day of the court case, the jury was shown a collection of drawings of the alleged crime scenes which Beech drew and handed over to officers to support his "false" claims.

Some depicted "demons" sexually abusing smaller figures while others were vague jottings about the locations where the supposed "paedophile ring" was said to have operated.

In one of the sketches, Beech described a pool where boys were sexually abused, writing on the paper: "Each man selected one of us.

"You then stuck with them unless they wanted to swap you with someone else. There would be a lot of touching."

Prosecutor Tony Badenoch QC told the court how Carl Beech told investigators that he hadn’t researched images of the crime scenes prior to sketching from his memory and providing the product to the police.

He said: "This was entirely contrary to easily accessible internet imagery and photographs of locations recovered from his own computer. It was like everything else a complete lie."
