One technician was killed while three others were killed in a suspected cylinder blast in the aero-dynamics laboratory of the Indian Institute of Science (IISc) in Bengaluru on Wednesday.
Four technicians of a private start-up company were carrying out an experiment at the IISc lab when the blast occurred at around 2.20 pm.
Manoj, one of the technicians from Mysuru, died on the spot while three others suffered injuries.
The injured have been admitted to a private hospital where their condition was said to be stable, police said.
Though the nature of explosion and its cause were yet to be established, it was suspected that the incident occurred due to a blast in a cylinder containing some gas, they said.
Assistant Commissioner of Police Niranjan Raj Urs told PTI that the start-up company Superwave Technologies Private Limited was having a tie-up with the IISc for carrying out experiments pertaining to its research.
“Forensic experts would ascertain the actual cause of the accident but it seems like a cylinder blast,” he said.
