A man raped a lesbian teenager in London after he refused to accept she was gay, a court has heard.
The 19-year-old woman was returning home from a concert with her partner and a friend when she was attacked in an alleyway, the Old Bailey heard.
Daniel Fountain, 20, from Staines, Surrey, denies rape and assault.
The attack took place in October last year after the trio bumped into the defendant and one of his friends at a bus stop, jurors were told.
Mr Fountain followed the teenager and tried to kiss her when she became separated from her partner and friend, the jury heard.
When she rejected his advances Mr Fountain became angry and aggressive and raped her, the court heard.
Bill Emlyn Jones, prosecuting, said: "He no doubt knew that she was drunk and she was perhaps therefore an easy target.
"She explained that she was gay. Fountain refused to believe this."
Mr Jones told the court that when the teenager returned to her friends she collapsed in the road.
The woman's partner became angry and punched Mr Fountain on the chin, the court heard.
Mr Fountain then hit her in the head before punching her friend in the face and running off, the jury was told.
He is charged with rape and assault by penetration, assault and causing actual bodily harm.
He denies all the charges. The trial continues.
