Four labourers died after they were exposed to poisonous gas inside a septic tank in Muzaffarpur in Bihar on Tuesday, officials told IANS. The labourers, who belonged to the same family and lived in the same village, were reportedly trying to clean the newly-built septic tank in a building that was being constructed in the Madhuban Kanti village.

District official Kundan Kumar informed that the labourers died due to suffocation after entering the septic tank to remove some material used for construction. "Prima facie, it is suspected that they died of suffocation inside the septic tank," he said. Kumar said the district administration will provide compensation to the victims' family under the disaster management fund.
