A serial flasher who exposed himself to teenage girls in a popular park on three occasions is still at large.

Surrey Police are appealing for witnesses following several reports of indecent exposure by a man in Ewell.

On three separate occasions, April 29, June 2 and June 6, a man has exposed himself to teenage girls walking through Nonsuch Park.

The first incident happened between 8pm and 8.40pm on April 29 when a 16-year-old girl saw a male touching himself on a park bench, who later followed her as she walked through the park.

On June 2, a man exposed himself to three girls near Nonsuch Park's gates on Ewell Road at 11am.

On the third occasion, a man exposed himself to three schoolgirls at 2.50pm near an entrance to the park from Ewell Road.

The pervert is a light-skinned Asian, of average build, with dark hair, and 6ft tall.

Detective Constable Hannah Millyard said: "These incidents have been very distressing for the girls involved.

"It may be there are further witnesses out there, who for whatever reason have not yet contacted officers with information, I would urge these people to do so as they may have information vital to our investigation.

"Officers from the Epsom and Ewell safer neighbourhood team have stepped up patrols in the area at key times in an attempt to prevent any further offending."
