A man was arrested after allegedly threatening to 'shoot everyone' and assaulting two patrons with a handgun at Seattle's Regal Thornton Place movie theater on Friday night. The incident began when the suspect, a 30-year-old Seattle resident, felt wronged by a fellow moviegoer who walked past his row of seats. The confrontation escalated, leading the suspect to brandish a handgun and physically assault two individuals, resulting in severe injuries. The suspect attempted to flee but was quickly apprehended by police and booked on multiple charges, including assault and felony harassment. Witnesses described scenes of panic as moviegoers fled the theater, and some tried to wrestle the gun from the suspect. The victims were treated for their injuries and transported to a local hospital.
