They were dubbed the terror hoarders of Lorong 8 Toa Payoh, stirring fear and disgust with their aggressive behaviour and unhygienic practices.
But on Saturday, the "terrors" - a family of three - appeared subdued as they waited patiently at the void deck of the block.
Their flat was in the final stages of disinfection after a five-day process of clearing their hoarded items, fumigating and washing.
The family also promised grassroots leaders that they would maintain the condition of their spruced-up flat.
The clean-up was initiated by their Potong Pasir MP, Mr Sitoh Yih Pin, over concerns of public hygiene and possible fire hazard. It was a joint operation coordinated by the HDB and it involved the National Environment Agency (NEA), the Potong Pasir Town Council and the police.
The trash disposed of amounted to 10.5 tonnes, said Mr Sitoh. But the process had a rough start.
Last Monday, a 55-year-old woman and a 20-year-old man became aggressive when cleaners removed things from a four-room flat on the 18th storey.
The New Paper reported on Wednesday that they were arrested by police for disorderly behaviour and later released on bail.
The flat belongs to a frail 91-year-old woman who suffers from dementia and is wheel-chair bound.
The two people arrested were her daughter-in-law and her grandson.
Mr Sitoh said he had been approached by other family members of the elderly woman, who were concerned that she was living in unsanitary conditions with the hoarded items.
Neighbours had complained of pests and a stench from the flat.
