Here are 10 developments in the story:
The boy surrendered last week after turning 18, which was four days after the accident. His father was also arrested but granted bail.
The juvenile board said the boy had been driving for two years and was penalised before. "Parents gave him a car, which endangered our lives. It's bad parenting," it said.
The teen was allegedly driving at 80 km an hour when the car hit marketing consultant Siddharth Sharma in the Civil Lines area.
The 32-year-old, who was returning home with take-out from a noodle stand, was hit so hard that he was flung 10 feet into the air.
CCTV footage showed that there was no sign of the Mercedes driver trying to avoid hitting him or even slowing down.
Last year, the teenager had been fined thrice - twice for speeding and once for parking wrongly.
The boy's father has been charged with aiding in the crime by allowing him to drive before legal age.
The police also arrested the man who claimed to be the actual driver of the Mercedes at the time of incident but backtracked after learning that Siddharth Sharma had died.
If found guilty, the teen - who was out celebrating with friends after his Class 12 exams when the accident took place - will be sent to a juvenile home for two years.
Siddharth Sharma's family has said that he should be tried as an adult and should not "get away with lighter punishment" on a technicality.
