Dinesh Gupta and the 17-year-old girl got trapped inside the car with its AC on after the vehicle ran out of petrol in Punjabi Colony of Narela at around 12.30 am, a senior police official said.
"They could not open the door before carbon dioxide got filled inside the car. After sometime Gupta managed to open the doors. In a semi-conscious state he came out, but fell down resulting in his death," the official said.
However, the girl was saved as Gupta opened the door to allow oxygen.
