Crazed attacks injure 4 Finest

Four NYPD officers were injured by unhinged New Yorkers in two separate attacks Monday — one involving a machete-wielding madman who slashed a sergeant across the head in Brooklyn.

In the first attack, three cops were sent to the hospital after responding to a report of an emotionally disturbed man inside an East Flatbush apartment on New York Avenue at around 3:30 p.m.

As officers spoke to family members inside the home near Beverley Road, the 40-year-old allegedly slashed the sergeant across the side of the head with the weapon, police said.

Two additional cops were cut in the wrist and shoulder while they put the man under arrest.

The three officers were taken to Kings County Hospital in stable condition and the suspect was taken into custody, with charges pending Monday night, according to the NYPD.

A little more than an hour later, a fourth NYPD officer was injured by another disturbed New Yorker at a Manhattan subway station.

In that incident, an MTA worker flagged down cops after a “disorderly” man was being combative with a group of teenagers inside the 42nd Street-Bryant Park station at around 4:45 p.m., according to police sources.

The officers attempted to remove the man from the subway station but he became irate and punched one of them in the left side of the face, cops said.

He was subsequently arrested, and charges against him were pending.

The attacks took place one day after a hit-and-run driver rammed an NYPD cop during a traffic stop in Manhattan. The injured officer was treated for minor injuries.
