A 27-year-old woman was found dead in a Woodlands Avenue 9 flat yesterday morning.
The police made the discovery at the third-storey unit of Block 878 shortly after receiving a call at about 9.30am.
The Singapore Civil Defence Force said its paramedics pronounced the woman, who was found lying on a mattress in a bedroom with no visible fatal injuries, dead at the scene.
The New Paper understands she was a Singaporean.
A 36-year-old man and a 31-year-old woman were subsequently arrested in relation to the case.
TNP believes the suspects are a Singaporean married couple who were friends with the dead woman.
When TNP went to the flat yesterday evening, nobody answered the door. There was no light in the unit.
A neighbour in the flat next door said the suspects and dead woman kept mostly to themselves.
He said the couple seemed friendly and would occasionally smile and say "hi" when they met in the common corridor.
Another neighbour living in a corner unit about 20 metres away said she and her mother "saw the police but were unsure what it was about".
When asked if they knew who lived there, the girl, who's in her late teens and declined to be named, said: "We have seen two women and a man in that flat, but we are not sure if all three lived there."
While they were not close to the people in the flat, they discussed a problem they faced last year.
She added: "We never spoke to them much, but last year we complained to each other about a nuisance stray cat which used to leave a mess along our corridor.
"Other than that, we saw them playing mahjong from time to time, so we named the unit 'the gambling house'."
Another resident on the fourth storey said that police had asked his daughter if she had heard anything from the unit below yesterday morning.
His daughter, who was asleep at the time of the incident, told the police that she "didn't hear anything at all".
He added: "We don't really hear a lot of noise from that particular household. They were not a nuisance or anything.
"Although we haven't spoken to them, we think the unit is a rental flat."
The man said he saw police officers outside the flat when he arrived home from work a little past 6pm yesterday.
Police have not classified the case as yet, but have not ruled out the possibility of foul play.
