Police Chief Dwight Henniger said Saturday night that authorities took one person into custody after the shooting at the Sandbar in West Vail.
Bar patron Nancy Lewis says she saw a man being escorted out of the bar and speaking incoherently. She says he then pulled out a gun and shot someone in the arm.
Other witnesses told the Vail Daily newspaper that the man fired several shots, then re-entered the bar and fired several more shots. Police received an emergency call at around 7:30 p.m.
Police haven't released the name of the shooting suspect and haven't named the victims.
