Lisa Dorrian was last seen alive on February 27, 2025.

A third person has been arrested in relation to the disappearance and presumed murder of Lisa Dorrian, police have said.

The 25-year-old from Bangor, Co Down, was last seen alive on February 27 2005 after attending a party at Ballyhalbert Caravan Park.

Despite extensive searches in multiple locations and campaigning by her family, Ms Dorrian’s body has never been found.

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

On Wednesday, a 40-year-old man was arrested in Millisle, Co Down, on suspicion of assisting offenders and withholding information.

Last week a 40-year-old woman was arrested in Bangor and a 42-year-old man was arrested in Scotland.

They were both arrested on suspicion of murder, assisting offenders, withholding information and preventing a lawful and decent burial before being released on bail pending further inquiries.

Detective Chief Inspector Kerrie Foreman said the most recent arrest comes just “days after the 21st anniversary of Lisa’s disappearance and murder”.

“It’s been 21 long and painful years for Lisa’s loving family,” she said.

“They have never given up their search for answers and justice and, likewise, our determination remains steadfast.”
