Hong Kong police have arrested an off-duty officer for allegedly assaulting colleagues who were responding to a noise complaint in a flat.

The force said on Tuesday that the 32-year-old man was apprehended on suspicion of attacking the officers who arrived at a Tsing Yi flat at 1am on Sunday to handle a noise complaint. He was said to have reeked of alcohol at the time of the offence.

Initial investigations revealed that the suspect was a police officer. He has since been assigned to administrative duties and suspended from carrying a firearm.

He was held in custody on charges of assaulting officers, obstructing police in the execution of their duties and failing to carry identification documents.

The Kwai Tsing regional crime unit is handling the case and has ordered the suspect to report to a police station next month after his release from custody.

The force stressed that it would take firm action against officers breaking the law.
