He removed his clothes and made comments in relation to engaging in sexual acts. During the incident on 4 July, he was chased away by another man. They both ran towards Queen Street and through the precinct towards the Royal Square.’
The suspect is described as about 5ft 9in tall, stocky build, with short dark hair and he was wearing dark blue jeans, a white t-shirt and black trainers.
