NEW video has emerged of Herald Sun columnist Andrew Bolt fighting back after he was sprayed with a "sticky liquid with glitter and dye" by masked men at a book signing in Carlton North on Tuesday.
Two protesters set upon Bolt, spraying him with the liquid, while a third offender filmed the incident.
Security cameras captured the incident and Bolt can be seen fighting back, kicking and "clobbering" the masked offenders.
Bolt told The Bolt Report viewers on Tuesday evening: "Bad luck for them; I don't do running and hiding."
"Police are now looking for this young man, who will have a big bruise on the left side of his face and another bruise between his legs, for which I apologise, I guess, but I don't really fight nice if I'm pushed too far," Bolt said.
Anyone who witnessed the incident at the Il Gambero restaurant in Lygon St is urged to contact North Melbourne police on 03 8379 0800.
