Queens police officials last week kicked off a “surge” against crime in Western Queens housing developments.

While overall crime continues to nosedive in the 114th Precinct, a series of isolated, violent incidents have occurred in local housing developments, police sources said. “Most of these incidents involve some type of weapon,” the sources said. “The violence factor is increasing. It’s time that the NYPD and Queens Housing police move in and take control.”

Sources said the surge is a show of force that will send an undisclosed number of cops into the Queensbridge and Ravenswood Houses over the next few weeks. Additional police, on foot and in marked NYPD vehicles, will patrol the housing projects and surrounding neighborhoods in stepped-up enforcement designed to drive down criminal activity, the sources said.

Police officials decided to step up enforcement after a July 6 incident at a local housing project when more than a dozen cops responded to break up a crowd in the early morning hours, the sources said.

Moments after they arrived at the scene, the cops heard gunfire coming from the crowd and spotted a knife-wielding man running away, police said. A police sergeant and an officer, who took off after the suspect, were assaulted by members of the crowds, who also tossed bottles at the cops.

Four people were arrested on weapons charges and for assaulting police in that incident. Officers involved in the assault were taken to a nearby hospital for treatment of injuries they suffered, police said.

“When criminals decide it’s OK to attack police officers in such circumstances, it is up to the NYPD to return with a show of force to take back the streets,” the sources said.
