Block 210 in Hougang, which is next to Kovan Market and Food Centre, is a four-storey tower with outlets on the first floor and flats above.
Around 1.50pm, CNA arrived at the scene, and a portion of the earth floor was closed out, causing some retail spaces, including a fruits kiosk, a gold shop, and a hardware store.
In the closed area, at least nine officers officers were spotted.
A fruit stall associate who works at the fruits kiosk told CNA that he entered the hardware store after witnessing an explanation and a guy stabbing a lady at least seven to eight times.
He claimed that the sufferer has been employed by the hardware store for between one and two years.  , A contractor who tried to intervene was injured in the process, said the fruit stall associate.
After hearing what transpired, an observer who went to the scene with a friend reported hearing a man stabbed a lady at the hardware store with a knife.  ,
