A teenage girl screamed for help as her boyfriend listened helplessly at the end of the line while she was attacked, a court was told.

Prosecuting, Alan Blake told the jury that the 18-year-old waitress had got off the train at Datchet at about 10.15pm on Wednesday, April 12 and walked along London Road in Datchet on her way to meet her boyfriend in Colnbrook.

Mr Blake told Reading Crown Court on Monday that 34-year-old Kapil Dogra had followed the teenager from the station all the way along London Road.

The jury heard that she gradually became aware of him, as he walked along a parallel access road and ended up in front of her.

Mr Blake said: “He grabbed her, put his hand across her mouth and said ‘don’t scream or I’ll stab you’.”

Mr Blake said the alleged victim had been talking to her boyfriend through headphones and screamed for him to get the police.

The jury was told he had been walking from Colnbrook to meet her ‘halfway’ and frantically dialled 999 while running in the direction he knew she was coming from.

Mr Blake said that Dogra pulled her into a wooded area and forced her to perform a sex act, before telling her to wait while he got away.

The wood is at the junction of Majors Farm Road, London Road and Ditton Road.

Police officers and her boyfriend found her in a ‘shocked and distressed state’ soon afterwards .

Dogra, who lived at High Street, Addlestone, was arrested six days later at London’s Swiss Cottage Station.

He has pleaded not guilty to four charges – one of oral rape, two of penetration and one of forcing someone to have sex without their consent.

Mr Blake said Dogra had told police he had gone to Datchet to meet his drug dealer and had inhaled cocaine in the lavatories at the Manor Hotel.

He denies all charges and told police that he had approached the 18-year-old girl in a ‘chatty’ mood because of the cocaine and that she had agreed to have sex with him after sniffing a line of his cocaine.

The trial continues.
