Over 40 passengers travelling in an MTC bus (27 D) had a miraculous escape on Saturday after the vehicle went up in flames near Purasawalkam.
The bus was going to Villivakkam from Foreshore Estate when the driver noticed smoke rising from the engine. He stopped the bus near Moksham Theatre and alerted the passengers.
All of them managed to get off the bus before it went up in flames.
Three fire tenders rushed to the spot and firemen battled for 30 minutes before dousing the flames.
An electrical short circuit is suspected to be the reason for the fire. The police are investigating.
