The RUC has arrested two men in connection with the murder of Ms Julie Hamill, whose naked body was found on Portstewart strand last week. Ms Hamill (28), a niece of SDLP MP Mr Eddie McGrady, was strangled some time after leaving Kelly's nightclub in Portrush, Co Antrim.
The RUC has so far spoken to more than 1,200 people and is studying security videotape from inside the club.
