A video emerged online showing an uncle being slashed in the head by another man wielding a chopper on 29 June, at Block 111 Jalan Bukit Merah.
The elderly man, Mr Chen, spoke to Lianhe Zaobao and said that he was attacked because of an argument that he had with the attacker over a change of $1 for fried dough fritters about 3 years ago.
He said that he only met the attacker 4 times, with the first time being when he went to Telok Blangah Food Centre to buy some fried dough fritters and was short changed $1 by the man.
They then argued with each other and he never went back to patronise his stall again.
Chen was with his friends at the coffeeshop on Wednesday morning watching other people playing chess when the fried dough fritters seller charged at him with a chopper.
Chen slipped and fell while trying to escape and ended up being slashed on his head, as passers-by threw chairs at the attacker to try and thwart him.
The attacker was eventually subdued and pinned down before the police came and arrested him.
Chen was sent to SGH where he got 7 stitches for his wounds.
