Three labourers working in a sewage plant in Mumbai have died after allegedly inhaling toxic gas.
The Times of India reports that a worker had entered the tank at Prem Nagar in Mira Road to clean the structure.
After complaining of feeling uneasy two others entered and all three collapsed.
Authorities said the bodies have been sent for examination and that, though the victims have not yet been identified, they are likely to be Bangladeshi nationals working illegally in the country.
