A horror movie convention promoter says it is assisting authorities following charges against actor Gary Busey involving alleged sexual offenses at an event in New Jersey earlier this month.

Busey, 78, was charged Friday with two counts of fourth-degree criminal sexual contact, one count of attempted criminal sexual contact and one count of harassment following alleged actions Aug. 12-14 at the Monster Mania Convention at the Doubletree Hotel in the Philadelphia suburb of Cherry Hill, police said Saturday.

Monster-Mania Convention said in a Facebook post that after attendees complained, an unspecified “celebrity guest was removed from the convention and instructed not to return.”

“Monster-Mania also encouraged the attendees to contact the police to file a report,” the company said, adding that behavior that compromised the safety and well-being of attendees would not be tolerated. “Monster-Mania will continue to assist the authorities in any and every way possible,” it said.

“It was about contact. It was about touching,” Lt. Robert Scheunemann told The Philadelphia Inquirer of the muliple complaints police had received about Busey’s conduct.

Busey, who lives in Malibu, California, was scheduled as a featured guest for all three days of the event.

Police did not immediately respond to a message seeking details. It also wasn’t clear whether Busey has an attorney to comment on the charges, and a representative didn’t immediately return a message seeking comment Saturday.

Busey is widely known as a character actor, largely in supporting roles, though he came to attention and was nominated for an Oscar for best actor for playing the title role in the 1978 film “The Buddy Holly Story.”
