Police have launched an appeal after a man approached two teenagers and showed them porn.

The 14-year-old girls were approached by a stranger on the Freemantle Common side of Peartree Avenue, at the junction with Spring Road on Friday.

Neither of the girls were hurt or touched when the man showed them his phone, which was playing pornographic material. He then walked off laughing.

The man has been described as white, with a pale complexion; 5ft 8in tall; and of stocky build with a chubby face and skinny legs. He was bald and clean shaven, and wearing beige shorts and a black t-shirt with grey writing on it and a band logo.

Anyone with information is urged to call police on 101, quoting ‘'44170219638’, or call Crimestoppers anonymously on 0800 555 111.
