Two men and a woman aged between 31 and 63 have been arrested by the Hong Kong police for allegedly making explosives and inciting others to intentionally do grievous bodily harm.

Superintendent Wilson Tam of the Technology Crime Division said on Tuesday that a 31-year-old man was arrested on Monday in a Wong Tai Sin public housing estate after the police noticed someone allegedly inciting others to intimidate police officers and judicial staff online.

During the operation, officers found a number of tools and materials that could be used for making explosives. The police took evidence, including 20 kilograms of chemicals, measuring cups, and wires, from a flat in the Wong Tai Sin estate.

A mini-storage unit in San Po Kong, which was rented by the 31-year-old, was also raided by the police. Around 10 kilograms of chemicals were found at the site. The police said that the chemicals and tools found could be used to make TATP and HMTD explosives.

Messages allegedly published by the arrested man on an online platform included calls to attack police headquarters and said that certain judges should be made to pay, Tam said.

According to the police, the other two people, who were also arrested at the Wong Tai Sin flat, were family members of the 31-year-old. Further investigation was needed for the police to understand whether the pair had any role in the alleged offence.
