SINGAPORE - He spotted a drinking group at a HDB block's void deck and asked them to clear the beer cans, but one of them shooed him away.
Angered, Manimaran Ramaswamy, 43, hit Mr Chen Xian Ping once on his head with a wooden stick before leaving in an incident last October.
On Wednesday (March 29), Manimaran was jailed for four weeks after he admitted to causing hurt to Mr Chen, 53.
The court heard that Manimaran had got into a verbal dispute with Mr Chen after telling the latter and his friends to clear their beer cans at a void deck after they were done.
After Mr Chen gestured at him to go away, Manimaran picked up a 1m-long wooden stick at a nearby worksite infront of Block 255 Kim Keat Avenue on Oct 29 and returned to hit Mr Chen.
Mr Chen went after him and pushed him to the ground. He and his friend held Manmiaran down. A passer-by saw the scuffle and called the police.
The court heard Manimaran had just finished consuming two cans of beer and was making his way home at about 12.30pm that day when he saw Mr Chen's group.
Mr Chen sought treatment at Tan Tock Seng Hospital where he was found to have suffered a 10cm-deep cut on his scalp.
The scalp laceration was stapled. He declined to be admitted for further treatment and investigation.
He was subsequently discharged against medical advice and referred to outpatient services for further follow-up.
Manimaran could have been jailed for up to two years and/or fined up to $5,000 for the offence.
