The man who was found lying at the foot of block 165A at Teck Whye Crescent has been identified as Mohammad Roslan Zaini, 35.
It was understood that he was stabbed in the chest and chased down the block, leaving a trail of blood all the way to the pavement. The suspect was arrested in the nearby housing estate. The weapon used for the stabbing is still not found. Both the killer and Mr Roslan were flatmates.
Mr Roslan was a divorcee who used to live with his ex wife and son in the same unit. Neighbours mentioned that the unit will be full of people every Saturday and CNB had inquired about the occupants if they were there to do drugs.
The killer used to sleep along the corridors and the staircase for two years before Mr Roslan invited him to stay in his flat six months ago. He informed neighbours that he invited the killer to stay in his house out of sympathy.
