A 54-year-old man was arrested after a fight broke out at a coffeeshop at Block 417 Yishun Avenue 11.
A video emerged online on 2 June showing two men fighting at the coffeeshop, with the bald man attacking another man wearing a blue shirt.
A man in a light green shirt then tried to hold the botak back but without success, and another man in a grey shirt then tried to approach them.
However, the beer lady then hit him with a chair that she picked up, before another woman carrying a sling bag grabbed the chair from her then threw it away.
The sling bag lady was heard shouting at them to stop fighting.
Background
The incident had apparently happened on 14 Maay at about 8.45pm, according to Shin Min Daily News.
A beer promoter told the Chinese paper that she heard that the man in blue was purportedly unhappy that the beer lady (as seen in the video) was pouring drinks for other customers but not him.
He then got into a confrontation with the botak and beer lady, and a fight then broke out.
Police investigating
The Singapore Police Force also told SMDN that a 54-year-old man was arrested for allegedly carrying out a rash act causing hurt.
They also added that a 57-year-old man was conveyed to the hospital conscious, and that investigations are ongoing.
