The mystery of the source of a foul odour from water supply in a Bukit Damansara condominium was solved after the dead body of a man was found floating in the water tank on Tuesday. Residents had reportedly started complaining about water smelling bad since May 7. One of them, 23-year-old Abbas, said he and his housemates continued drinking the water despite the smell because they thought the pipe was rusty. "We drank and bathed with the water for five days. It was only on Wednesday that we found out that the weird odour was caused by a dead body in the water tank," he said. Another resident said she was traumatised by the whole incident and is now buying mineral water from outside for consumption. According to police, the 43-year-old victim, Chuan Wan Chooi, was not a resident of the condominium and a missing persons report was lodged by his brother on May 9. Meanwhile, Prof Dr S Shamala Devi of Universiti Malaya has advised those who had consumed the contaminated water to see a doctor if they experienced symptoms such as fever, stomach ache or diarrhoea.
