Senior police officers said they were hanging from the footboard of the bus plying on route number 721 (Mongalpuri to ISBT). They were crushed as the bus grazed past a Bisleri tempo parked on the road.

"The Blueline bus was speeding as the driver was trying to overtake another bus which was coming from behind. The victims didn't notice the parked-wrongly tempo and were crushed between the two vehicles," said the senior police officer.

Both died on the spot and their bodies are at the Maulana Azad Medical College mortuary. The postmortem will be conducted tomorrow.

The men, natives of Bihar, worked in a jeans factory at Gaffar Market and were going to ISBT to pick up a relative. They lived in Todapur village in Inderpuri. Their families in Bihar have been informed of the incident.

The drivers of the Blueline bus and the tempo have fled after the accident. Both vehicles have been impounded. A case has also been registered at the Karol Bagh police station in this regard and further investigations are on.
