ABC News’ Maggy Patrick reports:

According to the New York Post, the New York Police Dept. is initiating an investigation after a video of on-duty police officers gyrating with scantily-clad parade dancers surfaced online.

The video shows two police officers dancing with passing dancers in the West Indian Day Parade in Brooklyn on Sept. 5. The dancers were bent over as the officers grinded closely against them as people cheered nearby.

This year’s festival was  much more violent than in years past.

Nine people were shot near the route of the parade, two died. One of the dead was a grandmother who may have been hit by a stray bullet during a shoot-out between police and two suspects. One of those suspects was also killed.

Shots were also fired just blocks away from New York City Mayor Michael Bloomberg was taking part in the festivities.

A police spokesman told the New York Post that the officers are being investigated.

Police Commisioner Raymond Kelly said he wishes that the officers hadn’t taken part in the provocative dancing, but also said he didn’t want to make too much of it, telling a radio station that it wasn’t unusual for police assigned to patrol the parade to get caught up in its rowdy spirit.
