A man was shot in the arm Saturday evening (June 2) during what was being billed as the first headlining show in 23 years for recently reformed thrash metallers MACE at the Northwest Metal Fest in Spanaway, Washington. The cancer fundraising event was being put on by a biker club called the Bandidos at Uncle Sam's American Bar & Grill.According to Q13Fox.com, a dispute occurred "when a small group of members of another biker club, Ghostriders, showed up, [and] one of the members tried to enter the bar while wearing his jacket. The Bandidos asked him to remove his jacket so as not to disrespect their club. When he refused, a group of Bandidos surrounded him. The Ghostriders member felt threatened, and reportedly pulled out a gun and shot a Bandidos member in the arm. He was then tackled by a friend of the victim, disarmed, and held for police." According to Northwest Music Scene, authorities are still sorting through conflicting accounts about what really happened and Ed Troyer of the Pierce County Sheriff's Office said that the shooter would also need medical attention because of the assault. Deputies were also looking for another man late Saturday that is also reportedly a member of the Ghostriders. That member is a 70-year-old blind man who fled the scene before officers arrived and he left his car at the event. A two-minute video report from KomoNews.com can be seen below.
