The rape of a man in Londonderry has been widely condemned as detectives appealed for witnesses to come forward.
The victim — whose age is not known — was walking in Lawrence Hill close to the Northland Road when he was attacked by a man between 2am and 3am on August 8.
It is believed he was then sexually assaulted in the grounds of Foyle Arts Centre.
Nearby residents said the car park of the arts centre was cordoned off for examination by police through much of Saturday. The area is monitored by CCTV cameras fitted by the University of Ulster, which owns the building.
Sinn Fein councillor Maeve McLaughlin condemned the attack. “Any sexual attack has no place in society. I would also say that the victim in all of this has to be fully supported in their trauma,” she said.
“I would call on the PSNI to use every resource at their disposal to crack down on the perpetrator.
“This has been doubly shocking because the majority of sexual attacks are carried out on women. But all sexual assaults need to be condemned, no matter who the victim is.”
SDLP councillor Mark H Durkan said the attack was “shocking”.
“Anyone who has any information should give it to police as it is worrying to think that someone who is capable of this kind of attack remains at large.”
A police spokesman said specially trained officers from the PSNI's rape crime unit in Ballymena were investigating the attack.
Anyone who was in the area at the time of the incident is asked to contact them on 0845 600 8000 or call Crimestoppers on 0800 555 111.
