( CNN ) -- In the decade following the September 11 , 2001 , attacks , four CIA officers directly collaborated with the New York Police Department to expand NYPD 's counterterrorism capabilities , according to a newly disclosed report . The CIA inspector general 's report -- completed in late 2011 , but just declassified in response to a Freedom of Information Act lawsuit by The New York Times -- raises concerns about the relationship between the organizations . The investigation found `` irregular personnel practices '' and `` inadequate direction and control '' by CIA managers `` responsible for the relationship . '' `` As a consequence , the risk to the Agency ( CIA ) is considerable and multifaceted , '' said a memo from Inspector General David Buckley to David Petraeus , who was the CIA director at the time . `` While negative public perception is to be expected from the revelation of the agency 's close and direct collaboration with any local domestic police department , a perception that the agency has exceeded its authorities diminishes the trust place in the organization . '' CIA agents are prohibited from taking part in domestic spying and the report 's release comes in the immediate aftermath of leaks by National Security Agency contractor Edward Snowden . The investigation was launched after an Associated Press story that alleged `` inappropriate CIA involvement in the activities of the New York Police Department , '' the inspector general 's report said . The AP reported that the NYPD Intelligence Division dispatched CIA-trained undercover officers into minority neighborhoods to gather intelligence on daily life in mosques , cafes , bars and bookstores . It said New York police have used informers to monitor sermons during religious services and police officials keep tabs on clerics and gather intelligence on taxi cab drivers and food-cart vendors , who are often Muslim . The New York Police Department blasted the report as `` fictional , '' at the time . A year ago , New Jersey Muslims filed a lawsuit against New York City , accusing police of using unconstitutional tactics to spy on them in the years after September 11 . The NYPD later said the surveillance never produced a lead that linked to a potential terrorist plot . While the inspector general 's report found no reason to order a full investigation into the relationship , it did note that the `` risks ... were not fully considered . '' NYPD Deputy Commissioner Paul Browne hailed the cooperation between the agencies . `` We 're proud of our relationship with CIA and its training expertise , which is in part responsible for the fact that the 11 years since 9/11 and the anthrax attacks soon thereafter mark the first decade in the last six in which there has n't been a single casualty of a terrorist attack in New York City , '' he said in a statement . `` Not that the terrorists have stopped trying .
