A second man has been arrested following the disappearance of a 21-year-old woman in County Antrim.
The search continues for Chloe Mitchell from Ballymena, who has been described as a high risk missing person by the Police Service of Northern Ireland.
She was last seen by her family on the evening of last Friday, 2 June, but was captured on CCTV in the early hours of the following morning.
Officers have been given a further 36 hours to question a 26-year-old man who was arrested in the Lurgan area on Friday.
A 34-year-old man was also arrested on Saturday in the Ballymena area and is assisting with inquiries in police custody.
Police say it is “completely out of character” for Ms Mitchell not to be in contact with her family.
Ms Mitchell was last seen wearing a green and black Northface style jacket, a white t-shirt, leggings and Nike trainers.
