Among the complaints, officers were found to have used batons and pepper spray on peaceful protesters in 140 instances. Dozens of allegations of abuse of authority, including officers refusing to identify themselves, concealing their badges and making false or misleading statements, were also substantiated, the report by Civilian Complaint Review Board (CCRB) said.
More than 600, or 43%, of misconduct allegations were closed after officers could not be identified, raising a big obstacle in the board's review, the report said.
