BROWNSVILLE - Police arrested 15 alleged drug dealers Wednesday after undercover officers purchased crack cocaine and marijuana near public schools.

Most of the sales occurred less than 1,000 feet from P.S. 174 on Dumont Avenue or P.S. 328 on Alabama Avenue, police say.

The NYPD operation began in August 2014.

In addition to the arrests, police executed six search warrants and seized an undisclosed amount of drugs and drug paraphernalia.

The 15 suspects were scheduled for arraignment at Brooklyn Criminal Court.
