Hong Kong (CNN) -- For the second time in a week, suspected Hong Kong organized crime syndicates -- known better as triads -- have targeted the production of "Transformers: Age of Extinction" being filmed in the Chinese territory. Four men attempted to extort an undisclosed sum of money from a crew member inspecting a rooftop shot location in the district of Kowloon Tuesday, the Hong Kong Police told CNN. Police arrested and charged one 35-year old man with blackmail but his three partners remain at-large. The attempted shakedown follows a suspected triad incident October 17 in which two men assaulted Transformers director Michael Bay.

Bay, 48, explained that every vendor that experienced disruptions from filming in the area "got paid a fair price for our inconvenience" but one man "wanted four times that amount" -- around $13,000 (100,000 @placeholder dollars).
