Glenn Danzig Is Named As Suspect In Alleged Assault On Fan

Exclusive Details

Metal god Glenn Danzig made a BIG impression on a fan this weekend -- unfortunately he allegedly made it on the fan’s face by beating the crap out of him, and now cops have launched an investigation.

The alleged victim, Neil Dalton, says 60-year-old Danzig stopped his Sunday night concert in Montreal to berate him for taking pics. Danzig famously has a "no photos" rule at shows, and Dalton claims the singer threatened to break his neck.

Dalton says the tongue-lashing was just the start -- he claims security dragged him outside, beat him up ... but inexplicably let him back into the show, briefly. He claims security hauled him out again, but this time Danzig showed up to join the beatdown. 

Montreal PD confirms Dalton filed a police report later that night, and they're investigating.

If this sounds familiar, might be because we got Danzig punishing another photo taker back in July.
