Over two dozen passengers travelling in a Blueline bus had a narrow escape Wednesday when it caught fire following CNG leakage, an official said.

The bus, plying on route number 181 between Jehangirpuri and Nizamuddin, caught fire around 7.25 a.m. near the Paharjganj area in central Delhi, the fire officer said.

'The bus caught fire after CNG leaked. The driver immediately vacated the bus and turned off the CNG system. He has suffered minor burn injures,' the officer added.
