allegedly hurled a chair off the rooftop of a Nashville bar Sunday night, narrowly missing cops on the ground. The blurry clip, obtained by TMZ, shows an unidentifiable object fly over the side of the roof of the Chief’s Bar and quickly plummet to the ground below on the busy downtown street. Wallen, 30, was arrested for allegedly tossing the chair over the edge of the sixth-floor rooftop of the Broadway bar, owned by fellow country singer Erich Church, just after 10:45 p.m.
