In a lawsuit filed Mar. 2 in Los Angeles and obtained by tmz.com, Gerald Rechnitzer, 27, claims he was at Teddy's nightclub at the Roosevelt Hotel in Hollywood with his girlfriend, after the Academy Awards.
According to the lawsuit, Rechnitzer asked his girlfriend to leave with him and Combs allegedly responded "what the f**k you looking at dude?'"
Combs then allegedly followed up by yelling, "I'll smack flames out of your ass!"
The lawsuit claims Combs then punched Rechnitzer in the jaw, him to fly backwards.
"At no time was Plaintiff, who is five feet, seven inches tall with a slim build, ever a threat to Defendant…." Rechnitzer's attorney said.
The suit alleges "after attacking Plaintiff, Defendant Combs intentionally, willfully and knowingly pushed Plaintiff's girlfriend and attempted to spit on another female member of Plaintiff's group."
As Combs was leaving the scene, the lawsuit claims the mogul "stuck the upper half of his body through an open passenger window of his vehicle and stared plaintiff down in a threatening and menacing manner thereby causing plaintiff to fear for his safety and the safety of his girlfriend."
The lawsuit seeks unspecified compensatory and punitive damages.
The LAPD said they are investigating the allegations against Combs and interviewing witnesses.
A representative for Combs refused to comment.
