A crazed landlord pistol-whipped a teenage girl in the head after she refused to break up a party at her East New York apartment, law-enforcement sources said yesterday.

Javier Wint, 49, allegedly flew off the handle Saturday night, whacking the 16-year-old in the head with the butt of a gun in the apartment on Pine Street, near Loring Avenue.

He was busted a short time later after he was pointed out by the girl, and was charged with assault, menacing and criminal possession of a weapon, the sources said.

The girl’s injuries were not considered serious.

Staten Island

A drunken man leaped onto a moving car in Graniteville early yesterday morning, sending it careening into parked vehicles just steps from the suspect’s home.

Sources said a sloshed James Crupi, 36, jumped onto the hood of the vehicle on Ada Drive just before 1 a.m.

The stunned driver lost control, smashing into two parked cars.

When rescuers arrived, the unhinged suspect leaped onto a Fire Department vehicle and tore off the windshield wipers before unleashing a verbal tirade at the workers, sources said.

Crupi, who sources said has prior drunken-driving arrests, was hauled off to Richmond University Medical Center, where he was treated for cuts.

He was charged with reckless endangerment, criminal mischief and resisting arrest, according to a spokesman for DA Daniel Donovan.

The driver was uninjured.
