American director and producer Michael Bay was injured on Thursday in an attack in Hong Kong during filming for his latest Transformers movie.
Two brothers surnamed Mak, aged 27 and 28, approached Bay on the set during filming for the American science fiction film and the younger brother demanded payment of HK$100,000 (S$16,075), a police spokeswoman told Reuters.
It was not immediately clear why the money was requested.
As a discussion ensued in a busy area of Hong Kong island, the elder Mak walked up and assaulted the director, the spokeswoman said. The elder brother then attacked three police officers who tried to intervene, she added.
The younger brother was arrested on suspicion of blackmail and assault, while the elder Mak was also arrested on suspicion of assault, she said.
Bay sustained injuries to the right side of his face, although he declined to seek treatment, the spokeswoman said, adding she did not believe his injuries were serious.
Filming continued after the dispute.
Bay was not available for comment. When Reuters visited the scene after the assault, the film crew and others working on the set declined to comment.
The three police officers were treated in hospital for minor injuries, while the younger Mak asked to be taken for treatment, saying he did not feel well.
Also arrested at the scene was a third man surnamed Chan.
All three are in custody and police are investigating.
In a post on his website, Bay gave his account of the incident:
"Hi, it's Michael.
"Yes, the story is being passed around is not all true! 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.
"Every vendor where we shot got paid a fair price for our inconvenience, but he wanted four times that amount.
"I personally told this man and his friends to forget it we were not going to let him extort us. He didn't like that answer. So 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.
"Then it took fifteen Hong Kong cops in riot gear to deal with these punks. In all, four guys were arrested for assaulting the officers.
"After that, we had a great day shooting here in Hong Kong. The place could be better."
