A day after three people were killed and one fell seriously ill, allegedly due to toxic gases, the Vatva police on Friday issued notices to the Ahmedabad Municipal Corporation (AMC) and the Gujarat Pollution Control Board (GPCB), seeking details of drainage connections in the area. This implies that the police primarily believe that the deaths were caused by poisonous gases that entered through the drainage lines.
Talking to DNA, police inspector and investigating officer KM Kapadia said that the notices were issued mainly to know the details of the domestic and the mega pipeline connections in the locality. “If there is any illegal connection, mainly from the industrial unit, then we can proceed with the investigation in that direction,” he said. However, the police would await the post mortem report before deciding on the next move.
Meanwhile, a forensic science official told DNA that they suspected that hydrogen sulphite in a very large quantity could have entered the lungs of the victims. “However, the exact report will come in a few days,” he added.
Member secretary of GPCB, Hardik Shah, told this correspondent that samples from all the industrial units in the locality had been taken and the board would proceed once the copy of the post mortem report was received. This would enable them to determine the source of the poisonous gas, he said.
Municipal commissioner Guruprasad Mohapatra has ordered a probe and sought a report from the city engineer. Only after receiving the report about sewerage water and effluents of the mega pipeline, the reason for the deaths could be known, he said.
Meanwhile, sources in AMC said that an illegal connection was found in a domestic sewerage line and another in the mega pipeline. There is a possibility that the mega pipeline gas might have come through domestic lines, but it can be known only after a detailed report, they added. The AMC has disconnected illegal connections of drainage.
