Four persons including three sanitary workers were found dead in a manhole in Ayyappa society in Madhapur area of Hyderabad. The civic officials suspect that toxic gases caused their deaths.
An employee of 108 Ambulance service, who tried to rescue them, fell ill after inhaling the poisonous gas, said R Kalinga Rao, Madhapur Police Inspector.
“The workers were cleaning the manhole. As three of them did not come out after going in, a local resident named Srinivas climbed down to rescue them but he too did not come out,” the police official said.
All four were found dead inside the manhole yesterday and their bodies were sent for post-mortem, Rao added. A Greater Hyderabad Municipal Corporation official said these four persons might have died due to inhaling poisonous gases.
