Manson was reportedly punched in the face by a 21-year-old man at a Denny's restaurant in Lethbridge, Alta. on Sunday morning around 2:30 a.m. after performing at the nearby Enmax Centre. (Insert your own "Grand Slam" pun here.)
Police confirmed to CTV News in Lethbridge that they were called to a disturbance at the Denny's on Mayor Magrath Drive near that time, and that one victim had "suffered minor injuries."
No charges were laid, and police have not confirmed that the victim was Manson, whose real name is Brian Warner.
Rumours about the incident startedswirlingon Twitter Monday after a local DJ and Lethbridge College student told his followers that Manson had been punched for calling a woman in the restaurant a "bitch."
While TMZ originally ran with this detail, citing "sources," the celebrity news site reported Tuesday that Manson was denying he had done anything to instigate the attack.
According to Manson's manager, the artist had been eating at the restaurant when two young women approached him for a photo. Manson reportedly obliged, but a man soon came "out of nowhere" and "sucker punched" him in the face.
Manson's manager also told TMZ that after being grabbed by security, the unnamed man began "screaming about blowing up Manson's next concert."
The shock rocker now intends to follow up with Lethbridge police to press charges and possibly sue the man, according to TMZ.
A witness who spoke to the Calgary Sun recalled a similar scene.
"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," said Johnny Scott, who was one of several fans eating at the Denny's location while Manson was there.
"They were just talking and the guy just punched him right in the face without any provocation," Scott said. "[The attacker] just took the shot and ran off right away."
Denny's has not issued an official statement on the matter, but did respond to a Calgary radio station's tweet about the incident to confirm that "no food was harmed" during the altercation.
Manson, who is currently promoting his ninth studio album The Pale Emperor, will continue his tour as scheduled according to his website. His next show will take place on Thursday at the MTS Centre in Winnipeg, Man. (which boasts two Denny's locations, for the record).
