Hoshiarpur, Jan. 11 -- Four members of a family were killed, and one was injured when their car collided with a Punjab Roadways bus near Dosarka on the Dasuya road on Saturday, apparently due to dense fog. The occupants of the car belonged to Himachal Pradesh's Chalet village and were on their way to the Amritsar airport when the car collided with the bus coming from the Pathankot side. All four occupants of the car died on the spot. The injured was rushed to the Hoshiarpur civil hospital. Police reached the spot and shifted the bodies to the hospital. The bus passengers, who remained unhurt, were sent to their destinations in other buses. The victims were identified as Sukhwinder Singh, Sushil Kumar, Brij Kumar, and Arun Kumar. Injured Amrit Kumar said that they belonged to one family. He said that they were all going to drop him off at the airport as he was to catch a flight to Croatia. Deceased Sukhwinder, who was behind the wheel, had retired from the Indian Army as a havildar, while the other three worked in a private company. "We started from the village at around 5am. I was sitting in the front, while my uncle Sukhwinder was at the wheel. I don't know what happened as I had dozed off. I only remember that there was dense fog," he said. Amrit Kumar survived the crash as the car door on his side opened after the crash, and he fell out of the car. Bhunga police post in-charge Gurmeet Ghumman said that a case was being registered against the bus driver even though the accident seemed to have occurred due to fog. Cops said the bus passengers remained unhurt as it was running at a slow speed. Police have registered a case against the bus driver, a native of Kahnwan, under various sections of the Bhartiya Nyaya Sanhita. Hariana station house officer (SHO) Kiran Kumar revealed that the driver had been arrested. The bodies were handed over to the kin after post mortem....
