A gay policeman has been accused of sexually assaulting a junior officer at a Christmas party.

Police sergeant David Stevens, of Avenue Road, Highgate, allegedly took advantage of the officer when he passed out drunk in a hotel bedroom on December 4th last year.

Stevens denies sexual assault. He admitted he was drunk at the party and said he and the officer had a “passionate embrace” on the bed.

A friend of the junior officer said he went to find him to tease him about drinking too much. He said he saw Stevens lying on top of the man and heard moans, which he believed sounded “not right”.

According to the Hampstead and Highgate Express, the court heard that when Stevens left the room, the friend then went to wake the man up, who appeared to say he had not agreed to any activity.

The man then allegedly became angry, punching walls and demanding to know what Stevens had done. He then drove home still over the legal drink-drive limit.

The colleague who reported seeing Stevens lying on top of the officer then dialled 99, sealed the room and told colleagues to guard it as a crime scene.

The alleged victim told police he could not remember anything between dancing downstairs at the hotel and being woken by a colleague to discover his trousers and boxer shorts had been pulled down.

Stevens said he thought the man may have been embarrassed at being seen in an “embrace” with another man.

The trial continues.
