An 18-year-old Galway student remains missing tonight, last seen in London, despite earlier reports saying he had been found.
Patrick Halpin, a DCU student from Loughrea, was last seen in Zoo nightclub off Leicester Square on Tuesday night.
Reports that he had been found tonight were denied by his family, with his sister Regina posting on Twitter that there had been "a mixup of information".
DCU student Patrick was on a college trip to London, but left the club to go for food and did not return to his hostel.
When he was last seen he was wearing blue jeans and a blue T-shirt.
