Michael Bay 'Attacked On Transformers 4 Set'

Director Michael Bay has been attacked by a man wielding an air conditioning unit on the set of Transformers: Age Of Extinction.

The action movie maestro found himself on the receiving end of an assault with the unlikely weapon - along with several other members of the film's crew on set in Hong Kong.

The would-be assailant apparently rushed onto set in the Quarry Bay area of the city and swung the unit at Bay's head, but the director ducked and wrestled the weapon from him.

Police are reported to have been called and arrested the man - who had been subdued by members of the crew - and three alleged accomplices.

Bay wrote on his blog: "Yes, some drugged up guys were being belligerent asses to my crew for hours in the morning of our first shoot day in Hong Kong.

"One guy rolled metal carts into some of my actors trying to shake us down for thousands of dollars to not play his loud music or hit us with bricks.

"An hour later, he came by my crew as we were shooting, carrying a long air conditioner unit. He walked right up to me and tried to smack my face, but I ducked, threw the air unit on the floor and pushed him away.

"That's when the security jumped on him. But it took seven big guys to subdue him. It was like a Zombie in Brad Pitt's movie World War Z — he lifted seven guys up and tried to bite them. He actually bit into one of the guards Nike shoe, insane. Thank god it was an Air Max, the bubble popped, but the toe was saved."

Bay claimed that it took 15 police officers in riot gear to arrest the perps - who are thought to have been Triad gangsters or linked to Hong Kong's mafia.

Mark Wahlberg was recently pictured in a still from the movie.
