Manhattan

A burglar wanted for a series of Manhattan computer thefts was nabbed in Atlantic City, authorities said yesterday.

Between April 13 and July 22, Frank Demedina, 44, and at least one accomplice struck five times at commercial buildings on Fifth and Eighth avenues, and on West 39th and Mercer streets.

In several cases, the two allegedly posed as movers as they whisked by security, broke into offices and carried off numerous computers, equipment, a digital projector and $17,310 in cash, authorities said.

Demedina was arrested Monday after he threatened an employee in an Atlantic City casino, sources said.

New Jersey police ran his name and learned he was wanted in the burglaries.

He was linked to those thefts through DNA and video surveillance, sources said.

A spokeswoman for the DA’s Office said Demedina was charged with burglary and grand larceny.

Queens

A thief posing as a landlord stole $6,000 from a prospective tenant to whom she promised to rent a Ridgewood apartment, authorities said yesterday.

Raquel Sanchez, 35, was living on the second floor of an apartment building at 80-84 59th St., sources said.

She allegedly told the landlord she wanted to move to a vacant third-floor unit and borrowed the landlord’s key to look at it, and apparently did not return it.

On May 25, Sanchez, pretending to be the landlord, showed the apartment to a potential tenant and requested $6,000 for rent and a security deposit, sources said.

She received the money and told the tenant he could move in two weeks later.

When he returned 14 days later, Sanchez told him the apartment wasn’t ready and declined to return the cash.

The victim alerted cops and Sanchez was busted Monday on charges of grand larceny and criminal impersonation, said a spokesman for DA Richard Brown.

Ronald Anderson, 54, walked into a store on Archer Avenue near 148th Street at 11 a.m. Monday and asked the owner for a quarter, sources said.

When the owner refused, Anderson shoved his hand into his pocket to simulate a gun and shouted, “Give me all your money,” cops said.

As the owner chased Anderson out of the store, the suspect knocked over the flower pot, sources said.

The owner called 911 and Anderson was arrested on charges of attempted robbery and criminal mischief, said the DA’s spokesman.

Police grabbed two suspects after a gunpoint robbery in Bedford-Stuyvesant, authorities said yesterday.

Lennie Taylor, 21, and Harold Spencer, 42, confronted a truck driver unloading items outside a store on Bedford Avenue and Clifton Place at 12:20 p.m. Tuesday, sources said.

Spencer allegedly pointed a gun at the driver and demanded money.

When the driver didn’t move, Taylor stole $1,138 from the truck and fled with his accomplice, source said.

The victim called cops, providing them with descriptions of the thieves, who were nabbed Wednesday.

A DA’s Office spokesman said the two were charged with robbery and menacing.

A thug was arrested for beating a man outside a Bensonhurst restaurant, law-enforcement sources said.

Gennadiy Odesskiy, 42 was with three friends in the eatery on Kings Highway near McDonald Avenue at 2 p.m. on Sept. 29 when one of them started arguing and cursing at the owner for unknown reasons.

Another patron made eye contact with Odesskiy, who allegedly shouted, “What the f— are you looking at?”

The patron and a companion ignored him and left.

Odesskiy and his pals allegedly confronted them outside and stole a cellphone and eyeglasses from one of them, then viciously beat him.

Odesskiy was arrested later that night and slapped with various charges, including assault and harassment.

A disgruntled employee at a building-maintenance company in Stapleton was arrested after he was caught on camera stealing a van from a company parking lot, law-enforcement sources said.

Investigators discovered the stolen vehicle at Chernak’s home and arrested him Wednesday.

Chernak was charged with grand larceny and criminal trespassing, according to a spokesman for DA Daniel Donovan.

Shearin told the officers he had bought the weapon for protection. Shearin was charged with criminal possession of a weapon, according to the Donovan spokesman.
