CHENNAI: A 47-year-old man died of asphyxiation while cleaning a septic tank at an apartment complex in Karapakkam on the Old Mahabalipuram Road, Wednesday.
Two persons were booked and one person was detained in connection with the case, said the police.

A private apartment complex that has about 270 houses had hired a private sewage cleaning contractor to clear the septic tank. The contractor engaged Arul (47) and Praveen (20) from Kovilambakkam along with Senthilkumar.

The other workers called the ambulance service and he was rushed to the Royapettah Government Hospital, where doctors declared him dead on arrival, a police officer said.
Kannagi Nagar police reached the spot and conducted an investigation. Police said the supervisor who was present on the spot to oversee the cleaning did not follow protocol. Police registered a case for offences including under section 304(i) (Culpable homicide not amounting to murder) and sections of The Prohibition of Employment as Manual Scavengers and their Rehabilitation Act, 2013 and The Scheduled Castes and Tribes (Prevention of Atrocities) Act.
