The NYPD’s Internal Affairs Bureau is investigating whether cops made racist comments on a Facebook page about West Indian Day Parade revelers.

No officers were questioned as of yesterday because probers were trying to determine which Facebook commenters actually are cops, a police source said.

Some commenters called participants in the annual Labor Day event “savages” and “animals.”

State Assemblyman N. Nick Perry, a Jamaican native, said the posting shows “a serious need” for “policies that send clear signals to officers that racism and bigotry will not be tolerated.”
