A 27-year-old Cheyenne man could face up to ten years in prison after allegedly threatening a pregnant woman with a knife.

According to court documents, police were called to Robert Campbell's apartment around 11 a.m. on May 13.

The victim, who'd been living with Campbell since December, reportedly told police that Campbell was drunk when he grabbed a knife and threatened to harm her and her unborn child.

She said she feared for her life and hid in a room while calling the police.

Campbell was arrested and charged with aggravated assault and battery-threatens with weapon.

Campbell is being held in the Laramie County Jail on $10,000 cash bond. His preliminary hearing is scheduled for May 24.
