Ahmedabad: Nine people were killed and 10 injured when a speeding car ploughed into a crowd gathered at an accident site on a bridge in Gujarat's Ahmedabad city on Thursday, police said.

A constable and a Home Guard jawan, who reached the spot after the first accident of a collision involving two vehicles, were among those killed in the incident, they said.

The accident took place at around 1 am at ISKCON bridge on the Sarkhej-Gandhinagar highway in Satellite area of the city when the Jaguar car moving at a very high speed ploughed into a crowd gathered there, the police said.

"At around 1 am, a Thar (SUV) collided with a truck at ISKCON Bridge on SG Highway. After receiving information about the accident, local traffic police and a Home Guard jawan reached the spot to manage the traffic and handle the situation. Out of curiosity, several bystanders also gathered at the spot to check what had happened," Satellite police station inspector KY Vyas said.

"When they were on the bridge, a speeding Jaguar car rammed into the crowd, killing five people on the spot, while four people died during treatment. The deceased included a constable and a Home Guard jawan. Ten people who received injuries were admitted to different hospitals," he said.

The car driver, Tathya Patel, was also admitted to a private hospital as he also received injuries, the official said.

According to sources, the angry bystanders thrashed the car driver and a video of it was captured by a person standing below the bridge.

Deputy Commissioner of Police, Traffic, Neeta Desai, said an FIR had been registered in this connection and the police would try their best to ensure the kin of the victims got justice.

"Nine people were killed and 10 to 11 people were injured in the accident. It does not appear to be a case of drunk driving. But our primary investigation has revealed the speed of the Jaguar car was extremely high. Since (car driver) Tathya Patel is under treatment, we will arrest him once doctors give the go-ahead," Desai said at the Sola Civil Hospital.

Most of the deceased and injured youth belonged to other cities and were living here as paying guests, as per sources.

After learning about the first accident, they went to the bridge out of curiosity. Minutes later, the speeding car came from Karnavati Club side and ran over the crowd, they said.

The parents and other family members of the deceased reached the Sola Civil Hospital and demanded harshest punishment for the accused.

The crossroads under the ISKCON bridge is a popular hangout spot for the youth during night hours, as they gather there to have tea and snacks.

Many people wanting to travel to other towns and cities also gather at the ISKCON crossroads to catch buses or private vehicles.
