A SEXUAL assault took place in Potters Bar yesterday (Wednesday) sparking an appeal for witnesses to come forward.

The incident took place at around 1.15pm in Oakmere Park when a pervert approached two teenage girls from behind and “touched one of them inappropriately”.

The girls ran off in the direction of the basketball court and the man walked towards the war memorial.

Dc Clare Edlin said: “We believe there was a girl wearing a pink puffa-style jacket walking her dog by the bottom of the lake and I am very keen to speak with her as she may have witnessed the incident.

“I would reassure people that we are following a number of lines of enquiry and although the girls were shaken, they were not harmed.”

She added: “If you were the girl described, or if you were in the area and believe you saw the incident, I would urge you to contact police as soon as possible via the non emergency number on 0845 33 00 222. Alternatively, you can call Crimestoppers on 0800 555 111.”
