A college student has sued Prince (search) and his bodyguard for allegedly assaulting him after he took a picture of the rock star as he was getting off a flight at Minneapolis-St. Paul International Airport.

Anthony Fitzgerald of Edina filed the lawsuit Wednesday in Hennepin County District Court.

The lawsuit says Prince's bodyguard, identified only as "Trevor," lunged at Fitzgerald "in an aggressive, threatening manner," then grabbed his digital camera, leaving him "stunned and humiliated."

The lawsuit over the Dec. 29 incident alleges assault and battery, loss of the camera and intentional infliction of emotional distress that left Fitzgerald anxious and unable to sleep.

Edina attorney Frank Berman said the lawsuit, dated Jan. 14, was filed Wednesday because Prince's "people" wouldn't accept a copy of it. Fitzgerald is asking the court for instructions on how to serve him with it.

Ronnie Lippin, a Prince spokeswoman, said she wasn't familiar with the lawsuit.
