A day after a car caught fire inside Mumbai's southbound Coastal Road tunnel, the BMC launched a public awareness campaign detailing emergency protocols, evacuation procedures and safety measures. The civic body urged commuters to follow tunnel guidelines during incidents such as fire, waterlogging or other emergencies.

While final report is awaited, fire brigade’s initial probe on car blaze inside Coastal Rd tunnel indicates customisation of the horn could have caused vehicle to catch fire. Divisional fire officer says faulty wiring during customisation could be to blame
