Muslim community and supporters marched near 1 Police Plaza when the secret surveillance program was brought to light.
The New York Police Department says it has disbanded a special unit whose efforts to try to detect terror threats in Muslim communities through secret surveillance sparked outrage.
The NYPD confirmed the decision on Tuesday.
The surveillance program by the NYPD Intelligence Division had come under fire by community activists who accused the department of abusing civil rights.
The program relied on plainclothes officers to eavesdrop on people in bookstores, restaurants and mosques. The tactic was detailed in a series of stories by The Associated Press and became the subject of two federal lawsuits.
The NYPD's decision to disband the unit was first reported in The New York Times.
