A veteran police officer escaped injury when he accidentally discharged his handgun at a Marine Police base on Stonecutter Island on Thursday morning.
It is the second such incident involving a Hong Kong police officer this year.
The 50-year-old senior constable, attached to the force’s Small Boat Division, was unloading his Glock 17 pistol when it went off about 7.15am.
“One shot was fired. No one was injured,” a police spokeswoman said.
A senior officer said the force was investigating whether the senior constable followed proper procedures when unloading the weapon.
Detectives from marine police regional crime unit are investigating.
The pistol was understood to have handed to the Forensic Firearms Examination Bureau to check whether it malfunctioned.
The incident occurred at the gun loading area in the base of Small Boat Division at the Government Dockyard at Ngong Shung Road. The pistol fired just before the officer was about to return it to the armoury after finishing his overnight shift.
According to police, there are strict guidelines in the use of such firearms.
The spokeswoman said disciplinary action would be taken if any misconduct on the part of the officer was proven.
In February, a constable accidentally discharged his revolver at Kwai Chung Police Station. The 40-year-old man was unhurt in the incident.
