Muslim groups and civil liberties advocates are applauding the decision by New York Police Department officials to disband a controversial unit that tracked the daily lives of Muslims as part of efforts to detect terror threats. But they say there are concerns about whether other problematic practices remain in place.

The NYPD said Tuesday it had disbanded the surveillance program by its Intelligence Division and that detectives assigned to the unit had been transferred to other duties within the division.

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.
