A PERVERT who sexually assaulted a schoolgirl in a Potters Bar park is being hunted by police.

The teenage victim was walking through Oakmere Park with another girl when they were approached by the man.

He started to chat to them, and then placed his hands up one of the girls’ skirts and touched her.

The young girls then ran off.

Police are now appealing for information and witnesses to the attack – in particular a group of boys who, it is believed, called out to the girls as they escaped.

Pc Glen Hawkins said: “I am very keen to speak with the boys who shouted to the girls as they were running as they may have vital information that could assist the investigation.

“I would also be keen to hear from anyone who was in the area and believes they may have seen the incident take place.”

The offender is described as a black man, aged between 20 and 30, with short black hair.

He was wearing a dark coloured cotton jacket.

The attack took place at 6pm on Thursday, November 25.

Call police with information on 0845 33 00 222.
