POTTSBORO, Texas (KTEN) — Thomas White of Pottsboro is behind bars after investigators said he threatened to kill his roommate. 

The victim told police that White, 35, put a knife against his neck several times and slid the blade across the back of his neck in a throat-slitting manner before he was able to escape. 

The Grayson County Sheriff's Office said they believed White may have been under the influence at the time of the incident. 

White was arrested and booked into jail when he tried head-butting one of the detention officers, investigators said.

White faces a number of charges, including aggravated assault with a deadly weapon and resisting arrest.
