Two potential witnesses to sexual assault sought by police in Antrim
Police in Antrim are appealing to the public for assistance identifying two men they say may have witnessed a serious sexual assault.
Detectives investigating the sexual attack on a teenager in Portrush are hoping to identify the two men featured in the above photograph.
They believe the men may have witnessed the attack which took place a short time later.
The CCTV still was taken in Kelly's in the town during the last week of August 2014, police said, and the attack took place outside the premises.
Detective Sergeant Jenny Carson said: "We are investigating a serious crime and we believe these two young men may have witnessed the incident.
"We do not believe they were involved but we would like to identify them so that we can progress the investigation.
"I would ask these men, or anyone who recognises them, to contact police so that our enquiries can be progressed. Please call us on the non-emergency number 101 or use the independent charity Crimestoppers on 0800 555 111."
