MONONGAHELA, Pa. (WPXI) — Monongahela City Police say a man repeatedly resisted arrest by using his head. 35-year-old Shawn Greenough was arrested on felony aggravated assault charges after a 911 call for a domestic violence situation. It happened just before 5 a.m. Saturday at a Monongahela apartment, where a woman says Greenough assaulted her. The responding officer reportedly had one of Greenough’s hands cuffed when the suspect turned around and head-butted him twice, in the ear and the forehead. Police say Greenough also hit his head on the wall, and then the police cruiser window, smashing it open. Greenough was taken to Monongahela Valley Hospital for his facial injuries, where police say he lashed out at medical teams and security guards. Greenough is scheduled for a preliminary hearing on this incident on June 29th in front of District Judge Mark Wilson.
