A teenager collapsed as he told a court how he was preyed on by a television actor in a theatre stairwell.
The teenager was overwhelmed as he recalled the moment he was allegedly assaulted at the age of 14 during a rehearsal for a show.
The actor, who cannot be identified because of his age, is alleged to have attacked the boy to prove to his girlfriend that he was bisexual.
Opening the case at Blackfriars Crown Court, in central London, Timothy Forster, prosecuting, said the performer sent his alleged victim a text message suggesting the pair should engage in a sex act in front of the girl.
He allegedly forced himself on the teenager in an internal fire escape at the theatre in July 2010 after the boy refused his advances.
The next day, he raped him at the same theatre, jurors were told.
Further incidents took place on a weekly basis over a six-month period, "none of which he wanted," Mr Forster said.
Jurors heard how the TV actor's girlfriend first approached the teenager during a rehearsal and broached the subject of
"Later that same day, (the actor) came up to him and asked if he had spoken to (his girlfriend) and then, out of the blue, he said to (the boy), 'I think I'm bi'," the prosecutor said.
"(The boy) took it to mean he was telling him, 'I am bisexual'.
"(The actor) then asked (the boy) to come downstairs with him."
The boy refused and that night the actor sent him a string of text messages "to say that he had to prove to (his girlfriend) that he was bi and saying that he wanted to 'do it' with (him) and do it so that (his girlfriend) could watch," Mr Forster said.
The next day, he "grabbed" the boy, "pulled him down the stairs" and performed a sex act on him, jurors were told.
The teenager, who gave evidence from behind a curtain, struggled to compose himself as he recalled the alleged episode.
"He forced me to go down there, I didn't want to go down there," he said.
Proceedings were briefly adjourned when the teenager was asked to detail what happened and was unable to respond.
But he collapsed soon after the hearing resumed, when asked to expand on the alleged attack in the stairwell.
Jurors looked on in shock as the court heard a thud from behind the screen and the hearing was adjourned for a second time.
The jury was later sent home for the day.
The TV actor denies one count of oral rape in July 2010 and three counts of sexual assault between July 2010 and
All of the allegations relate to one victim.
The hearing was adjourned until tomorrow.Suggest a correction
