THE BRONX

*** Cops are asking for the public’s help in finding this man (above) for robbing numerous livery drivers in the north Bronx, authorities said.

The bandit first struck a month ago when he climbed into a town car on Rochambeau Avenue, brandished a knife and demanded the driver hand over money, police said.

The stick-up man has robbed five more drivers since then – the most recent being Thursday evening. In that instance, the cabby put up a fight and was injured during the struggle, police said.

*** Police are searching for a man who robbed a Chelsea bank after claiming he had a bomb in a bag, law-enforcement officials said.

He also passed a note demanding money and the teller gave him an undetermined amount of cash, cops said.

*** Police are asking for the public’s help in catching a brazen stickup man targeting ATM users at an Upper East Side bank over the past two months.

The thief is described as a black or Hispanic man, between 35 and 40 years old, 5-foot-10 to 6 feet, 180 pounds, with black hair and a goatee, police said.

QUEENS

*** A woman was busted for trying to scam a South Jamaica check-cashing shop out of thousands of dollars, police said yesterday.

Tiffany Roberts, 28, of Staten Island, told a teller at Check Busters on Merrick Boulevard that she was expecting a Moneygram for $9,000 on Monday morning, sources said.

When the worker told her that the reference number she gave him wasn’t valid, Roberts made a cellphone call.

Then the teller received a call from a “Mrs. Lopez” – an apparent co-conspirator – who identified herself as a Moneygram agent and said the transaction was aboveboard.

After handing Roberts the cash, the teller discovered that a “Mrs. Lopez” did not work for Moneygram and that the reference numbers provided were indeed fake.

Roberts was charged with grand larceny, said a spokeswoman for DA Richard Brown.

BROOKLYN

*** A man was busted for robbing a Flatbush jewelry store at gunpoint, police said.

Timothy Hairstone, 40, along with Kirk Hayles, held up the Splendid Jewelry store at 2846 Church Ave. last September, cops said. The two men allegedly pointed a gun at the store manager.

The thugs had the store employees lay on the floor as they took rings and watches, cops said.

They also demanded that the manager open a safe in the back of the store, although she told them she didn’t have the combination, and they fled without harming anyone, cops said.

After a yearlong investigation, Hairstone was arrested on Thursday and charged with robbery, attempted assault, petit larceny, grand larceny and harassment. Hayles had been arrested in May.

*** A Bedford-Stuyvesant man was arrested after pouring beer on a man and then stabbing him with a broken bottle, police said.

The victim, whose name was not released, had double-parked his car and stopped in a grocery store for a bottle of water on Aug. 3 at 3:50 a.m.

As he stepped out, Barry Williams, 26, allegedly spilled beer on the victim’s head and pants.

The victim then took the bottle and poured the remaining beer on the floor.

At that point, several other men emerged and attacked him, cops said.

One of the assailants pushed the victim on the floor and threw a garbage can on him, police said.

Williams then took a cracked bottle and stabbed the victim in the back, cops said.

The group fled, and cops were able to locate Williams a month later.

The victim, who had suffered minor injuries, was able to identify his attacker in a lineup, sources said.
