A Lewiston man beat up a woman in Casco early this morning and at one point threatened to kill her before releasing her and running away, according to the Cumberland County Sheriff’s Office.

Deputies arrested Corey P. Waugh, 27,  at 6 a.m. on charges of assault, criminal restraint, criminal mischief and criminal threatening, according to a statement from the sheriff’s office. He also is on probation for domestic violence but the alleged victim in today’s encounter, Farrah Downey, 33 of Casco, is an acquaintance of his and not in a relationship with him, the sheriff’s office said.

Downey told police that some time before 5 a.m., she was in a car arguing with Waugh when he punched her then dragged her from the car, deputies said. He then slammed her face into the pavement and bit her thumb, deputies said.

Waugh forced her back into the car and started driving to Lewiston saying he was going to kill her and himself, deputies said. Downey convinced Waugh to release her and he returned to her home on Tenney Hill Road. Once free, Downey started screaming for help and Waugh ran.

Deputies arrested him on Route 11 about an hour later.

Downey suffered a serious bruise on her head, a possible concussion and cuts and bruises on her face, head and thumb, deputies said. She was treated and released from Bridgton Hospital.
