"Three people were injured when a DTC bus hit a car before ramming into a subway crossing in west Delhi's Naraina on Thursday", police said.
A senior official said, "the Delhi Transport Corporation has ordered an inquiry into the accident."
"The driver, conductor and the marshal of the bus suffered injuries. They have been taken to the Metro hospital in Ranjit Nagar", they said.
"The two passengers of the car, which was on its way to Naraina Industrial Area from Gurugram, are stated to be safe", police said.
"There were no passengers on board the DTC bus that was on its way to the Naraina bus depot," police said.
During enquiry, it was found that the DTC bus was going towards Naraina Depot after dropping all the passengers at the stop.
"The bus collided with a car near the subway of Naraina flyover. To save the car, the bus rammed into the metro crossing," Deputy Commissioner of Police (West) Ghanshyam Bansal said.
"The driver, conductor and the marshal present in the bus were injured and two persons in the car are safe," he said.
According to the MLC, Rohtash (driver) and Gaurav (marshal) got minor injuries on their forehead and hands while Ramesh (conductor) suffered injuries in his abdomen and is under treatment in the Metro Hospital.
"Two men named Jasjog Singh and Eknoor Singh, both residents of Gurugram who were in the car, are safe," he added.
Another police officer said, "The driver told police that the break of the bus had failed which led to the accident. However, a mechanical inspection will be conducted by experts to determine the exact cause which triggered the accident."
The government official said, "the front side of the bus rammed into the subway crossing".
Meanwhile, the DTC Karamchari Ekta Union claimed that while the driver escaped with minor injuries, "the conductor''s entrails came out as an impact of the accident."
His condition is serious while the bus marshal had to get stitches on his head, the Union claimed.
A huge accident was averted due to the driver's alertness and many lives were saved.
The accident happened due to break failure.
"A thorough inquiry should be initiated in the matter," they said.
Sources at the hospital said, "The driver and other staff have sustained injury in their heads, while the conductor (Ramesh) has suffered injury in his abdomen, and is currently undergoing a surgery. Ramesh''s condition can only be assessed after the operation is over," a source told PTI.
Police are looking at footage from CCTV cameras installed in and around the scene to establish the sequence of events. Currently, the bus driver is injured... and is being treated at the hospital. Once his conduction is stable, he will be arrested in connection with the incident.
"A case was registered under sections 279 (Driving or riding on a public way so rashly or negligently as to endanger human life, etc) and 337(Causing hurt by act endangering life or personal safety of others) of the India Penal Code," the police added.
