Police are investigating an indecent act in Newport last month.
Investigators have been told a man exposed himself to three young girls at a park at the intersection of Margaret Street and Graham Street at 7.50pm on Monday 9 December.
The man is perceived to be Caucasian, about 50-years-old, with balding hair.
He was wearing a dark green jacket and dark pants and had a dark coloured larger-sized dog.
Investigators have released a face image of the man who they believe may be able to assist with their enquiries.
