A man claiming to be a bounty hunter was busted for impersonating a police officer in the Bronx, cops said Tuesday.

Michael Sorensen, 39, was allegedly wandering around Yankee Stadium subway station Saturday just after 4 p.m., decked out with a bulletproof vest, pepper spray, two radios, an expandable baton, a folding knife, and a B.B. gun holstered in his nylon gun belt, cops said.

Actual police officers followed him onto a train, where he was questioned and identified himself as a “bounty hunter,” cops said.

But when the wanna-be criminal-hunter couldn’t produce law enforcement ID or a carry permit for his pistol, cops slapped the cuffs on him, police said.

NYPD Transit cops tweeted about the arrest, noting that Sorenson was carrying a phony firearm.

He was charged with impersonating an officer and criminal possession of a weapon, police said. The Bronx District Attorney’s Office declined to prosecute the case, an NYPD spokesman said. A phone call to the DA’s office after business hours wasn’t answered. Calls to phone listings for Sorensen weren’t returned.
