Detectives have released an image of a man they wish to speak to after two women were assaulted in Northolt.
Police were called to Church Road at 9:28am on Wednesday, 10 August following reports that a woman had been the victim of a sexual assault.
Officers attended and provided support to the woman. Enquiries established that the alleged assault took place in the nearby underpass at the White Hart roundabout shortly after 5:00am.

“I urge anyone who recognises this man, or who was in the area at the time of these incidents and saw anything suspicious, to come forward.” Anyone with information should call 101 with the reference 1980/10AUG.
