Hells Angels rivals set to turn NYC into ‘powder keg’

New York City’s biker woes will get worse unless cops increase enforcement — because arch rivals of the Hells Angels are moving in and violence is likely to follow, the nation’s top expert on motorcycle gangs told The Post.

“It’s a powder keg,” warned Steve Cook, a Kansas City-area cop who has trained peers on how to deal with biker gangs and has worked with the NYPD.

California and Las Vegas have suffered amid the foothold gained by two Hells Angels foes, the Mongols and Vagos, with daylight shootings and murders at popular resorts, Cook said.

And now, the groups have begun establishing themselves in New York City, said Cook and NYPD sources.

“So far, the Hells Angels have been the only major outlaw club we’ve had problems with, and they were bad enough,’’ one NYPD source said.

The NYPD has seized 1,440 motorcycles, quads and dirt bikes this year. Cops have made 437 arrests.
