Two men are still being held in connection with the murder of a missing shop assistant in Northern Ireland.
The men, 18 and 23 years of age, were arrested yesterday. A third man who was also arrested yesterday was released this morning.
Lisa Dorrian (25), of Bangor, was last seen at a party at a caravan park in Ballyhalbert, Co Down, on February 28th last year.
Last week, graffiti identifying one of the main suspects in the murder of Ms Dorrian was daubed on walls. The graffiti, which named one of the last men to see her alive, said: "Tell the police where Lisa's body is and live."
Despite a huge search operation across land and sea, the woman's body has not been found.
It is believed that Ms Dorrian had become friendly with a crowd with suspected paramilitary connections.
Several men have been questioned about the disappearance, including the man whose name appeared on a wall near the loyalist Village district of south Belfast, in Bangor and along the Ards Peninsula.
It is thought he was with Ms Dorrian when she left her home in Bangor to go to the caravan site.
