A retiree with an arsenal of air guns was jailed for six weeks on Thursday for shooting and injuring a resident in a neighbouring block of flats.
Lee Chee Kum, 50, had pleaded guilty to committing a rash act that had endangered the personal safety of other people.
He also admitted to illegally possessing weapons that included 13 air revolvers, the air rifle, two knuckle dusters, and a stun gun with a torchlight function and was fined $5,000.
A district court heard that at 1.40pm on Oct 5 last year, Mr Bibish Meyama, 38, called police to complain that a neighbour was shooting plastic pellets into his 10-storey flat in Kim Tian Road in Tiong Bahru.
When police arrived, he pointed out Lee's window in the next block of flats.
Before allowing police officers into his 12-storey flat, Lee hid the air guns in a cupboard. But they were found and investigations revealed that Lee had shot the M4 replica rifle at a small target box on the windowsill of his bedroom.
He was trying to adjust the rifle's aiming mechanism and had fired about 10 pellets. One of these had hit Mr Meyama in the chest, causing him to scream out in pain. The restaurant owner did not seek medical treatment.
