Hong Kong police said a self-made remote-controlled explosive device aimed at "killing or injuring" police officers were detonated during the protest on Sunday. Due to the outbreak of anti-government unrest, the violence has escalated to the fifth month.
Deputy Commissioner Tang Ping-Keung said at the press conference: "It exploded less than two meters from the police car."
Mr. Tang said that this was the first time that an explosive device was used in a protest initiated by the controversial extradition bill in June, and it has since rapidly developed into an anti-government, anti-police and anti-China movement.
