Former Hong Kong 3D printing technician pleads guilty to inciting copycat attacks on police after July 1 stabbing

Lai Chit, 36, pleaded guilty to incitement to wound with intent at the District Court on Wednesday over provocative posts he made on the popular LIHKG forum, a Reddit-like online platform.

He admitted to calling for attacks on police officers a day after the fatal incident outside Sogo department store in Causeway Bay on July 1, 2021, when former Vitasoy purchasing agent Leung Kin-fai drove a dagger into constable So King-cho’s back, before stabbing himself in the chest.

A jury determined the 50-year-old attacker’s death to be a suicide during an inquest last year.

Posting two comments in a thread titled “A technical discussion: how should we use a knife?”, Lai wrote about a blade needing to be sharp with appropriate curves to “stick through chest or back muscles, as well as cloth”, recommending a chef’s knife for its ability to “easily cut into a big piece of fillet”.

The 36-year-old also detailed how to pierce flesh for maximum impact, and commented on Leung’s death.

“I don’t really want brothers-in-arms to kill themselves after assassinating [someone] like Uncle Leung. However, if someone reaches the depths of despair, others can’t completely counsel you. Hope everyone takes good care,” Lai wrote.
