Mel Gibson is off the hook for an accused assault on a photographer at the opening of a Hollywood nightclub on July 29, according to a police source.

Gibson refused to co-operate with authorities, said the source, who added that the star “won’t let us interview him”.

But the Los Angeles Police Department has dropped the case. The photographer in the incident had filed a battery complaint with police.

The police source told RadarOnline.com: “I went to the nightclub that night [July 29] and talked to many witnesses, who refuted all statements made by the alleged victim. The victims never saw an altercation by the two and never saw Mel allegedly rip the man’s T-shirt.

“From my point of view and extensive investigation it would be physically impossible for both men to touch each other.”

The LAPD has now turned the case over to the Los Angeles City District Attorney’s office. The official said the case “will be rejected for lack of evidence” at the DA’s office.
