A worker and his supervisor died after inhaling poisonous gases while cleaning a sewer chamber in Rabale, MIDC on Saturday evening. The Rabale police have arrested a site engineer for not providing safety gear to the workers.

The incident took place on December 3 when site engineer Dattatray Girdhari, who works with Bitcoin of India Pvt Ltd, told supervisor Sandeep Hambe, 35, and three workers—Vijay Jharkhand, 29; Vasant Jharkhand, 49; and Murtaza Sheikh, 30—to clean a choked sewer chamber at plot number 310 in MIDC. “Vasant and Vijay entered the gutter and Sandeep followed them. I was standing outside and collecting the mud and filth they filled in a bucket. Around 3.15 pm, suddenly a strong smell emanated from the gutter and the three fell unconscious. Vasant was moving a bit and I managed to bring him out with the help of a rope,” Murtaza said.
