Police have issued CCTV images of a man they want to speak to in connection with a serious sexual assault in central London.
A woman in her 30s had been on a night out when the suspect approached her in Lexington Street, in Soho.
They then walked around the area before the victim was assaulted in a lift at the NCP Brewer Street car park.
The incident happened at about 0650 GMT. The suspect left the scene after he was spotted by a witness.
The victim was taken to hospital and was then referred to a Haven Centre, which cares for victims of sexual assault.
The suspect was described by police as a black or mixed-race man and aged between 20 and 30.
He has short or shaved hair and is of a medium build.
The man was wearing a striped grey and black hooded top, jeans and white trainers.
Det Sgt Brian Richards, leading the investigation on behalf of the Westminster Sapphire unit, said: "Soho is a busy area of London and we believe there will have been people in the area who saw this man."
