She was arrested on suspicion of murder, assisting offenders, withholding information and preventing a lawful and decent burial, and remained in police custody on Wednesday evening.
Detective Chief Inspector Kerrie Foreman urged anyone with information about Ms Dorrian’s disappearance to speak to police.
“The arrest comes just days before the 21st anniversary of Lisa’s disappearance and murder,” she said.
“Lisa was last seen alive on the night of Sunday 27 February 2005 in Ballyhalbert in County Down, and we believe she was murdered that night or in the early hours of the following morning.
“We remain determined to provide justice for Lisa’s family, and I would appeal to anyone with information about her disappearance and murder to contact detectives on 101.”
