Five labourers who were supervising and also carrying out repair work to one of the water chambers at August Kranti Maidan's Nana Chowk, Grant Road, late Saturday night were rushed to hospital after complaining of uneasiness. While four suffered injuries, one was brought dead to Nair hospital.

Following drowning cases and reports of labourer deaths owing to working inside sewer lines, the BMC had decided that no more manual cleaning of sewers or of storm water drain lines would be carried out and if contractors or employees of the BMC were caught doing so, the BMC would take immediate action against them. But, rules are rarely followed.
