Man and woman arrested on suspicion of Lisa Dorrian's murder

Two arrests have been made in the investigation into the disappearance and murder of 25-year-old Lisa Dorrian.

A 40-year-old woman was arrested in Bangor, County Down on Wednesday and, later, a 42-year-old man was arrested in Scotland on suspicion of murder, assisting offenders, withholding information and preventing a lawful and decent burial.

Lisa has not been seen since she attended a house party at a caravan park in the County Down village of Ballyhalbert, at the end of February 2005.

Police acknowledged the support of Police Scotland, as well as the PSNI's Cross-Border Transit Officers in the arrest of the man in Scotland.

PSNI Det Ch Insp Kerrie Foreman said: "It's almost 21 years since Lisa's disappearance and murder. That's 21 years of torture for a loving family.

"I am keen to take every opportunity to encourage anyone with information to do the right thing and come forward."

"We remain determined to provide justice for Lisa's family," Foreman added.

Police believe Lisa was murdered on the night of 27 February 2005 or in the early hours of the following morning.

The PSNI appealed for anyone with information to contact them.
