LUCKNOW, April 22 -- Panic spread among passengers aboard a moving CNG city bus in Lucknow late on Monday evening after smoke and sparks allegedly emerged from the engine, forcing several commuters to jump off in fear for their lives. Officials said an explanation has been sought. The incident occurred in the PGI police station area when the bus was travelling from Kamta to Scooters India. Eyewitnesses alleged that smoke started emerging from the engine nearly 3 to 4 km before the vehicle was finally brought to a halt. The bus with registration number UP 32 DN 2928, operated from the Dubagga depot, eventually stopped near the Shaheed Path service lane in Utrahtia after the smoke intensified. Officials said the situation became chaotic because the bus was carrying around 56 passengers in a 39-seater vehicle. Amar Nath Sahay, city transport managing director, said the bus should have been stopped immediately after complaints were received. "The assistant regional manager has been asked to provide an explanation," he added. The bus is part of an ageing CNG fleet introduced in 2008 and has already been listed for auction in the coming days. A fire that broke out in Malha village under Dubagga police station limits on Tuesday afternoon left one person injured and caused significant damage to property, livestock and stored food grain, officials said. According to a police statement, the control room received information about the fire at around 2.44pm, following which local police teams alerted the fire department. "With the combined efforts of firefighters and villagers, the blaze was brought under control before it could spread further," said Dubagga SHO Srikant Rai. The police statement further added that multiple households suffered losses in the incident. A grocery shop owned by Ramvilas was completely gutted in the fire. Mohit, son of Mahadev, sustained burn injuries while attempting to control the flames. In addition, a buffalo was burnt alive in the incident, while one Ramchandra lost 13 goats in the blaze. Stored wheat and fodder belonging to Kisna, wife of Ramkishan, were also destroyed, adding to the overall losses faced by villagers. Police said the exact cause of the fire is yet to be determined. "The situation is under control, and further assessment of damage is being carried out. Necessary legal action will follow," an official said.
