A Good Samaritan turned into a one-woman swat team, bashing a suspect with a police officer’s nightstick after the cop dropped it during a struggle.
Rochelle Griffin, 39, of Brooklyn, had just hopped off a bus when she saw the officer chasing a man down Fulton Street in Boerum Hill at 1:15 p.m. Friday.
Moments earlier, a worker at a nearby Payless Shoe store had dialed 911 to say a man in the shop was carrying counterfeit bills — but ran off, police said.
The clerk gave a description of the man, which was broadcast over police radios, and an eagle-eyed cop spotted him, stopped him and asked for identification.
The suspect, no master criminal, pulled out his wallet, exposing a cache of bogus $10 bills, police said.
Then he took off.
That’s when Griffin came on the scene. She threw her purse at the suspect, later identified by cops as Shakhawat Hossain, 21, but he kept going.
Then the officer caught up to Hossain — and during the struggle, the baton was passed to Griffin. She used it on the suspect’s head.
Griffin told cops she had seen the suspect reach for the officer’s gun.
After doctors stitched up his head, Hossain was charged with 36 counts of possession of a forged instrument and resisting arrest, cops said.
