TMZ has learned that a big New York PR shop hired P. Diddy's former chief of staff to be their marketing point man in Sundance -- only to see the guy totally ditch them on the first day of the festival!
In a lawsuit filed in New York, 5W Public Relations alleges that Akil Rucker took the post of Director of Marketing -- and a $250,000 budget -- to get the party started for several of the firm's clients at the Sundance Film Festival.
"Akil Rucker has tremendously damaged 5W Public Relations and will be held responsible. We can't comment any further on legal matters," said Ronn Torossian, CEO of 5W Public Relations. Akil Rucker wasn't immediately available for comment.
