Neighbours of a man who allegedly stabbed to death a former air stewardess heard shouting and screaming coming from his flat.
Neo Chun Zheng, 26, was arrested in connection with the murder of 23-year-old Soh Yuan Lin in Boon Lay Drive on Thursday night.
Police received a call from a unit at Block 268B at about 8.15pm and found her lying lifeless at the scene.
Neo, who lives with his parents and older brother in a four-room HDB unit on the 11th floor, is believed to have stabbed the former Scoot stewardess in the neck with a 10cm blade outside his unit.
She was taken to Ng Teng Fong General Hospital where she was pronounced dead about three hours later. The Straits Times understands that Miss Soh completed a tourism management diploma at Ngee Ann Polytechnic before becoming an air stewardess with budget carrier Scoot.
When The Straits Times visited the flat yesterday morning, bloodstains could still be seen on the walls near the common rubbish chute. Neighbours said they heard a man and a woman quarrelling for about 10 minutes.
One, who wanted to be known only as Mr Su, said that Neo's mother was also present and could be heard frantically urging the pair to stop their argument.
"I thought it was just an ordinary quarrel between a couple," said the 50-year-old renovation technician who lives on the same floor.
"But when the mother shouted at me to call the police, I realised it was serious. I walked out of my flat and when I was about 5m away, I saw a woman lying face down in a pool of blood."
He said that Neo remained at the scene until officers arrived.
Madam Yang, a 36-year-old housewife living on the same floor, was in her bedroom when she heard Neo's mother screaming: "Why are you carrying a knife? You will go to jail."
Later, she heard a short high-pitched scream, followed by a woman sobbing uncontrollably.
Mr Nicholas Teo, a 24-year-old who described himself as a friend of the victim, said Miss Soh and Neo had dated for a while before breaking up. When she started seeing other men, he began to harass her, added Mr Teo, who is studying in Melbourne.
