The incident happened at around 3.40pm on Thursday, 18 March at Trinity Road car park, situated between St. Mary’s Road and St. Andrew’s Road.
A woman was walking through the underpass below St. Andrew’s Road when she saw a man exposing himself. The man then followed her towards her car and attempted to gain access to her vehicle, but she managed to drive away.

He has also been arrested on suspicion of three sexual assault offences and two indecent exposure offences relating to separate incidents.
He has been questioned by officers and released on police bail, with conditions, while our enquiries continue.
