The police watchdog, the Independent Police Complaints Council, says it will review over 600 complaint cases against officers filed so far during the anti-extradition protests, which began in June.
Around 220 have been filed by the alleged victims. Most relate to allegations of misconduct and neglect of duty.
Some IPCC members were concerned that officers could not be identified, after some riot police and special tactical squads failed to show their warrant cards or identification numbers on their uniforms. The force now says officers will display their identification on their helmets.
The chairman of the council, Anthony Neoh, said helmet ID may not be enough but the panel can also locate an officer from other information, such as police rosters.
"We cannot be one hundred per cent sure, that even though there is something visible on the helmet, that sign is caught by the camera or caught by photographs," he said.
But Noah said, because there is so much there in the public domain and with the police concerning deployment, this information can sometimes be triangulated.
