A 47-year-old Singaporean man has been arrested for allegedly killing a man at a Teck Whye Lane temple.
Mr Tan Poh Huat, 53, was struck on the back of his head with a hammer in the early hours of Feb 14.
A pest control worker found him lying motionless in Chua Chu Kang Lian Sing Keng temple. The worker had also seen a 2m trail of blood outside the prayer hall.
Mr Tan's sister, Madam Tan Sui Kee, said closed-circuit television footage showed a masked, tattooed man climbing into the temple in the middle of the night.
Mr Tan was reportedly a runner for a bookie and was carrying $10,000 at the time of his death. But there was no money on him when he was found.
A police spokesman said the arrest was made following protracted investigations.
