Police are hunting a man following sex attacks on three women in north-west London.
In each of the separate attacks in Brent on the evening of March 6, the women were approached from behind before they were sexually assaulted, Scotland Yard said.
They were walking alone in the Neasden, Dollis Hill area between 7.30pm and 10.45pm.
A fourth incident was reported in the same area at about 1am on March 24. Detectives are keeping an “open mind” as to whether the incidents are linked.
The Metropolitan Police have released a photograph of a man they want to speak to, believed to be 25 to 35, of Asian or Mediterranean appearance and of medium build. He was said to be wearing a dark bomber jacket, dark trousers and a black hat at the time of the attacks.
Detective Sergeant Steve Sussex, who has been leading the investigation, said: “We would encourage women to be vigilant when walking home in the evenings and, where possible, to stick to well-lit areas.
“We are working tirelessly to catch the perpetrator or perpetrators.”
Anyone with information should call police on 101 or Crimestoppers anonymously on 0800 555 111.
