A SEX pest groped a 13-year-old girl as she walked home from the park with her sister and a friend.

Police are appealing for witnesses to the incident in Bramble Park, Taunton, at about 8.40pm on Friday.

The man, who had been sitting under a tree near to the play area in Holway Park, approached the girls before following them along Haywood Road.

He then ran past and waited for them to reach Bramble Park, where he inappropriately touched the victim’s bottom.

The girl screamed and the culprit ran off along a nearby footpath.

He is described as white man, aged 40 to 50, around 5ft 5ins tall, of chubby build, with thin grey hair.

He was bare-chested and was wearing white underwear or very short shorts with a stripe down the side and was carrying a black bag.
