An alleged rapist has claimed a teenager beckoned him over for sex in a park and nodded her consent.

Mojitaba Changi, 33, of Lea Bridge Road, Walthamstow, is jointly accused with Saeed Fatemi, 20, of the same address, of anally raping the woman, then 18, in Canbury Gardens last September.

He told Kingston Crown Court on Monday that he had followed Mr Fatemi and the woman into the park and seen them "playing around" with their trousers down.

The three had walked through Kingston town centre after Mr Changi and Mr Fatemi visited a club. They had been staying together with an acquaintance in Kingston.

Mr Changi said he had wanted to go home but that Mr Fatemi, who was drunk and preoccupied with the woman, had not heeded his request to hand over a key.

He said that after he reached the park, and Mr Fatemi and the woman had ended their sexual activity: "She was gesturing. Saeed stood up and she came towards me and she started to touch me.

"She touched my chest area and she touched around my private area."

He added: "I asked her twice with both hands thumbs up. She said OK with the head."

Mr Changi, an Iranian tyre dealer and father of two, denied he had forced himself on the woman or held her down, and denied penetrating her anus or vagina. Instead, he said, he rubbed his penis between her legs.

But last Friday prosecutor Sally Fudge told the court that DNA sample taken from semen inside the woman's anal canal matched Mr Changi's.

Semen found on the woman's jeans matched Mr Fatemi's, she added.

Last week Miss Fudge told the court the pair were accused of a "brutal attack on a young and vulnerable girl who was barely into adulthood".

Mr Fatemi chose not to give evidence in the trial, his lawyer, Nathan Palmer, said on Monday.
