An elderly man was on Thursday mowed down by a speeding Blueline bus after being hit from behind in south Delhi, the police said.
The accident occurred in the morning when the bus plying on Route No 463 hit the bicycle rider, who was yet to be identified, near the Asian Market in Mehrauli area.
The bus driver managed to flee from the spot, while the victim, who appeared to be in his 50s, was taken to a hospital, where doctors declared him brought dead.
Police said bus was impounded and a search for the driver was on.
"We have registered a case and investigations are underway," said a police official.
The 'killer' Blueline buses have already claimed more than 15 lives this year. At least 120 people were killed last year in accidents involving the private buses.
The 4,000-odd Blueline buses, a crucial part of Delhi's public transport system, have earned public ire for the recklessness of its drivers and owners but officials say they are helpless to check the menace.
