According to TMZ, Marilyn Manson wants police to arrest the man who assaulted him and the shock-rocker's makeup artist inside a Denny's restaurant in Alberta, Canada the night of April 4, shortly after Manson performed a show at the Shaw Conference Center.
Manson's manager told the site the singer was sucker punched in the face after he agreed to pose with two females who asked for a photo.
Eyewitness Johnny Scott told the Calgary Sun the assault was unprovoked.
"Manson never got a chance to sit down," he said.
"He was being friendly with everyone, anyone who wanted a picture, he would give them a picture, anyone who wanted an autograph he would give them an autograph.
"They were just talking and the guy just punched him right in the face without any provocation.
"He just took the shot and ran off right away, then I remember seeing him in the parking lot ducking behind cars, he looked terrified."
According to Scott, Manson's nose was bleeding after the incident.
"It was a good shot, but I don’t think it broke his nose," Scott said.
"I ended up hanging out with Marilyn Manson for a little while afterward... He was pissed off because he was being nice."
Marilyn Manson is currently on the spring leg of his "Hell Not Hallelujah" tour in support of his latest album, "The Pale Emperor".
The trek next stops in Winnipeg on Thursday (April 9) and will conclude May 13 in Grand Rapids, Michigan. Manson will hit the road once again in July for a string of co-headlining shows with the SMASHING PUMPKINS.
