Police are increasingly concerned about a flasher who has struck seven times in Oxford.

The man has exposed himself to women at a bus stop, leaped out from behind trees and blocked the path of three of his victims while riding a bike.

Police, who believe seven incidents between February and April are linked, fear the man is becoming bolder.

He stopped in front of three women and exposed himself while riding a bike near McDonald’s at the Green Road roundabout in Headington, on Sunday, April 26, at about 1.45pm.

They managed to push past him and ran off.

Sgt Yak Teladia said: “In most of the incidents he exposes himself without speaking or threatening any members of the public. In the incident in London Road his behaviour has escalated slightly, by attempting to block the women from escaping.”

The victims have described the man as white, in his late 20s, about 5ft 9in and skinny.

He has short, dark hair, is clean shaven and wears scruffy clothes. He was riding a blue mountain bike and carrying a black rucksack in Headington.

Anyone with information should call police on 08458 505505 or Crimestoppers on 0800 555111.
