An image has been released by police hunting a man who is accused of sexually assaulting a 12-year-old girl at a swimming pool in Woolwich.

The girl and a friend were visiting Waterfront Leisure Centre at around 2.30pm on Saturday, January 7.

While she was swimming she was reportedly approached by a man who sexually assaulted her.

Detective inspector Steve Birchall, of the Met’s sexual offences, exploitation and child abuse command, said: “The children in this case have been targeted in a public swimming pool. The person in the image knew they were children and has acted extremely inappropriately towards them.

“It is important we identify him to safeguard children in the same circumstances when they should be able to swim and play safely.”

The suspect is described as being around 30-years-old, with black cropped hair, stubble and a goatee beard.

PC Emilie Gurney, also of SOECA, said: “I am urging anyone who may know or recognize the male in this E-fit image to contact us.

"Anyone who may know the man's identity should contact Operation Sapphire on 020 8721 4612 or via 101."
