A doorman described how two teenagers left a club with their arms around each other.

But he said the girl was upset when they returned 40 minutes later to the Planet nightclub in Brighton.

The girl alleges she was raped by a 17-year-old youth in the graveyard at St Nicholas's Church in Dyke Road. Neither can be named for legal reasons.

The incident was filmed on January 24, by a couple who live opposite the graveyard and have complained about youngsters having sex there.

Hove Crown Court has heard they gave tapes of incidents they recorded to the police and city council as evidence of what was happening there.

The video was played to the jury on Wednesday after Judge David Rennie ordered the public to be excluded from court because of its sensitive nature.

The girl, who is also 17, was at Planet for a friend's 18th birthday party and met the defendant, who she already knew, there.

Door supervisor Mohammed Amin said yesterday he saw the two leave the club as if they were girlfriend and boyfriend.

Mr Amin said: "When they came back the girl was walking in front of the boy and her body language was different. She was really upset about something.

"I went in to check on her and she was talking to her friends."

Mr Amin said he walked out of the club with her and saw her and her friends into a taxi.

He said the boy was still outside the club and he told him to stay away from her because she was too scared to see him again.

Cross examined by Jeffrey Lamb, defending, Mr Amin agreed he had seen the teenagers kissing and cuddling in a shop doorway opposite the club before they walked off.

He said the girl appeared to leave willingly with the boy but was hurrying down the hill ahead of him when they returned to the club.

Mr Amin said: "I went in to see if she was alright and she was crying and said she wanted to go home. I was told by her friends that she had been raped."

He said that the boy was still outside the club and there was a lot of shouting about what had allegedly happened.

He agreed with Mr Lamb that the defendant had shouted: "I didn't do that. Do you think I am crazy?"

The court heard yesterday that lip reading experts had seen a video of the incident to try to determine what was being said during the alleged rape.

Mr Lamb suggested that at one point the girl was telling the defendant: "I do not want to do it here."

She told the jury of nine women and three men: "No, I was not saying not here. I was saying no I did not want to do it."

The trial continues.
