The Oxford County Sheriff’s Office is looking for a missing Buckfield teen who they describe as “at-risk.”

Hannah Thomas, 15, has been missing since last Thursday.

She was last seen at her home in Buckfield.

According to CBS 13, the sheriff’s office says the teen frequently runs away.

She has previously been found in the Lewiston-Auburn area after leaving home.

Last November, she was located in North Carolina after running away.

Hannah is 5-7 and about 125 pounds.

She was last seen wearing gym clothes, black sweatpants and black sneakers.

Anyone with information on her whereabouts is asked to contact their local police department or the Oxford County Sheriff’s Office.
