Police have arrested a 29-year-old man on suspicion of manslaughter after his friend died last week from a skull injury sustained during a drunken altercation in Sheung Shui.
The 29-year-old suspect was arrested on Sunday night after giving a statement at Tai Po police station. The victim, engineer Chan Tat-wang, 27, had been declared dead in hospital that same evening.
Chan had been out for a hot pot dinner and a four-hour drinking session with the suspect and three other friends on Friday night before he got into a scuffle with one of them.
The group, who had known each other for years, went to a bar along San Kin Street in Sheung Shui at about 10pm after a regular gathering.
They left the pub at around 2am on Saturday, when the fight broke out. Chan is believed to have pushed a friend, who then pushed back at Chan, causing him to fall.
Police made the arrest after studying CCTV footage of the altercation. '[Chan] fell backwards and the back of his head hit the ground,' a police officer said. 'They all appeared to be quite drunk when they left the bar.'
'After viewing the CCTV tapes, we found out what happened. We arrested one of [Chan's] friends,' the officer said.
Chan is said to have been in semi-conscious after the fall but his friends, seeing no obvious injuries on him, believed he was drunk and flagged down a taxi to take him home to Kat Cheung Crescent in Fanling.
Chan, who shared the home with his 36-year-old girlfriend, complained to her of headaches, but she also believed him to be drunk and put him to bed.
She called an ambulance at 2pm on Saturday when she was unable to wake him up.
Doctors at North District Hospital discovered a skull fracture and placed him in intensive care. Staff at the hospital notified police of the man's injury.
The four friends gave statements at the Tai Po police station later on Sunday night.
Nobody has yet been charged with any offence.
The three other friends from Chan's party were allowed to leave after helping with the investigation. Detectives from the Tai Po district crime squad returned to the scene in San Kin Street yesterday afternoon to conduct further inquiries.
