HONG KONG (AP) -- Police are investigating a second reported extortion attempt at the Hong Kong film set of the latest "Transformers" movie.
A government statement said a production company crew member was setting up on the roof of a building in Kowloon on Tuesday when four men "intimidated her and ask for money."
She called police, who arrested a 35-year-old man. He's being held pending further inquiries. The three others are still wanted. The case has been classified as blackmail.
Police arrested two brothers last week after director Michael Bay was assaulted at another filming location. They allegedly demanded 100,000 Hong Kong dollars ($13,000).
"Transformers 4: Age of Extinction" is partly set in Hong Kong. It's set for release in June 2014.
