Police are hunting a flasher with a limp who exposed himself to two teenage girls and two teenage boys on Friday.

The middle-aged man, believed to have a limp, followed the teenagers after exposing himself in Headley Grove, Epsom, just after 9pm.

The young teenagers, aged between 13 and 15, immediately called the police to report the slim white man who was wearing a black leather jacket and hooded top.

Detective Constable Michael Queally said: "This is a deeply concerning incident, not only the nature of the offence and the age of the victims, but the man followed the teenagers as they attempted to quickly leave the scene.

"Thankfully, the victims were able to get to a place of safety and did the right thing and called police immediately with a detailed description of the offender, and they should be commended for their actions.

Police are carrying out patrols and making enquires in the area in a bid to find the flasher. He was about 5ft 5in, aged between 40 and 50 and had dark baggy jeans on.

DC Queally said: "We need to trace the man involved in this incident as a matter of urgency, I would urge anyone who either saw a man matching the description of this offender in the area around the time of the offence or who has their suspicions around someone they know, to contact police."

Anyone with information should call police on 101, quoting reference 45150016579.
