BROOKLYN - Nearly 2,000 police officers are being retrained today after a civilian review board found excessive complaints against them from residents living in public housing.

The Civilian Complaint Review Board says in 2009 it found a high number of complaints from people saying they had been improperly stopped by police who patrol within and around buildings owned by the New York City Housing Authority.

While these officers are allowed to stop people, the CCRB says they can only do so if they have reasonable suspicion of a wrongdoing. The board then recommended several officers be retrained.

The officers began their retraining in June, according to the New York City Police Department. They are expected to be finished by the end of November.
