The Delhi government on Monday, September 10 ordered a probe into the death of five labourers following inhalation of toxic gas while cleaning a sewer tank in West Delhi's Moti Nagar, and sought a report in three days.

A statement by Delhi's Labour Ministry said the incident took place on Sunday, September 9 in DLF Green Apartments in Moti Nagar.

"The Labour Minister wants a fact-finding inquiry conducted so as to decide further course of action against the defaulting agencies/firms," it added.

On Sunday, around 3 pm, the apartment staff informed the police that five labourers were trapped in a sewerage, Deputy Commissioner of Police Monika Bhardwaj had said.

They were pulled out and taken to the hospital where Sarfaraz, Pankaj, Raja, and Umesh were declared brought dead. Vishal, who was admitted to the RML Hospital in a critical condition, died during treatment, the officer said.

Union Minister and Lok Janshakti Party leader Ram Vilas Paswan called the incident "shameful and inhuman".

"The LJP has been demanding for years an immediate ban on manual cleaning of sewer drains. For this, a law should be made immediately to provide for strict action and the guilty should be punished with imprisonment of at least 10 years," he said in a statement.
