Hong Kong police have arrested four people after seizing suspected gun parts, more than 140 rounds of ammunition and a 3D printer capable of making weapon components during a series of raids across the city.
The four were detained on suspicion of possessing firearms and ammunition without a licence, among other offences, said Superintendent Ng Chung-wai of the organised crime and triad bureau on Tuesday. Officers were still investigating the intended use of the weapons, he added.
A report made to police on Sunday night led officers to the Hing Man Estate public housing block in Chai Wan, where they found 138 bullets for a 9mm pistol stored in a plastic bag on a staircase.

Police arrested a 31-year-old estate resident and his 36-year-old girlfriend, while inside the man’s flat, officers found a 3D printer, gun parts they suspected were made with the machine, a USB thumb drive containing a blueprint for manufacturing weapon parts and three magazines.
Lying in ambush on a staircase, officers also arrested a 25-year-old man who they suspected was picking up the ammunition.
In his flat in Tsuen Wan, police found five sets of suspected gun parts, nine bullets, four machetes and three respirators. His co-tenant, aged 33, was also arrested.
According to Ng, the 31-year-old man worked as a decoration contractor and his girlfriend was employed in the catering industry. The 25-year-old suspect was an IT worker and the 33-year-old man drove a taxi.
