Three cleaners died while working at a manhole in the city on Sunday triggering a protest by their fellows.
They were Farzem Sheikh, Hasi Sheikh and Suman Sardar from Murshidabad. The tragic incident took place at Sector 6 Industrial Development Authority in Bantala Leather Complex at around 9 am. Farzem,
Hasi and Suman were busy cleaning chemical waste from a high drain.
Suddenly, a pipeline that was used through the ten-ft-deep manhole for cleaning the drain exploded. One of them lost balance and fell inside the manhole. To rescue him, two more got down one after another but could not come out.
