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 or $12,900, 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.
