The New York City Police Department has once again found a partner in crime prevention in the form of social media.

This week, the NYPD busted some four dozen “suspected gang members” after tips emerged on Twitter that a “Crips Holiday” was being planned and arranged on the microblogging platform – a public mechanism by which authorities were able to monitor the developing situation.

According to the New York Daily News, arrests were made at Amersfort Park in East Flatbush on Wednesday.

They ordered the crowd, who were mostly dressed in the distinct blue colors of the gang, to disperse from the park. When they refused, cops moved in and rounded up 56 of the gang-bangers, a police source said.

A 9-mm. Taurus pistol was subsequently recovered inside the park, authorities revealed.

“We don’t know exactly what their intentions were,” another NYPD source added. “But a gun was recovered. The potential for danger was there.”

The NYPD recently established a new Juvenile Justice Unit, “which monitors social media websites for gang activity”
