Officers say the suspect, 50, knifed himself in the chest after stabbing and critically injuring a 28-year-old officer in Causeway Bay, right outside the Sogo department store. He was subsequently pronounced dead in hospital.
Sources said officers found a suicide note in a USB flash drive found on him, which explained his actions.
The note was reportedly critical of the police and contained views on how the national security law had undermined people’s freedom.
A raid at the suspect’s home, meanwhile, found a number of materials in his computer as well as newspaper clippings relating to the 2019 social unrest.
RTHK was told that the suspect was not married, and did not have a criminal record or a known history of mental illnesses. He lived with his parents, but it’s said that they didn’t know what their son did for a living.
Meanwhile, the condition of the injured officer – who was from the force’s tactical unit – had improved from critical to serious. His lung was said to have been punctured in the attack.
The police have classified the case as attempted murder and suicide, while security chief Chris Tang had described the attack as a “lone-wolf style act of domestic terrorism.”
In light of the stabbing, a police spokesman told RTHK that the force will continue to assess the effectiveness of their operations, review officers’ needs, and consider all necessary measures to improve operation efficiency.
These include strengthening training and introducing suitable equipment.
On top of that, sources say frontline officers have been told to patrol in a group of two or more if manpower allows.
The police will also reportedly step up its scrutiny of online messages to prevent potential copycat attacks, and front-line officers may wear protective vests while policing crowd management events in future.
Also on Friday, some people clad in black were seen leaving white flowers at the scene of the attack, with officers stopping some of them for identity checks.
A woman wiped tears from her face, and a young man holding a placard that said “don’t die” offered free hugs to passers-by outside the shopping centre.
