Police in the North are treating 21 year old Chloe Mitchell as a 'high risk' missing person.
They claim it's 'completely out of character' for her not to be in touch with her family.
The 21-year-old was last seen in Ballymena a week ago.
Searches teams are scouring the Braid River and surrounding areas.
Superintendent Gillian Kearney is issuing this appeal:
"Please look at the photograph of Chloe. She was last seen wearing a green and black NorthFace jacket, a white t-shirt, leggings and light trainers. I would like to thank the public and the search-and-rescue teams for all their help so far in trying to find Chloe".
