The family driver, according to the report, has told the police that the driver drove the Porsche out of the pub's valet.

"The family's driver told us that the teenager drove the Porsche from their Wadgaon Sheri bungalow to Cosie and later to Blak Marriott pub. The driver and another employee followed the Porsche in another four-wheeler. After partying at Blak Marriott, the driver drove the Porsche out of the pub's valet," the DCP was quoted as saying by the TOI report.

According to driver, the teenager insisted on driving the Porsche despite being drunk, DCP Zende said. "The driver called the teen's father, who instructed him to let his son drive. He asked him to sit in the passenger seat. The driver complied, and the teenager drove with two friends in the back seats before the accident occurred," the officer said.

The Pune police on Thursday also questioned the 17-year-old boy's grandfather, who allegedly also has links with gangster Chhota Rajan, in connection with the car accident. A forensic team examined the Porsche car involved in the accident on Thursday, an official said.

A friend of the accused teenager and the driver who were accompanying him in the car when the accident occurred in Kalyani Nagar area, were also questioned by the crime branch officials who are probing the case.

"Since the luxury car is in the name of the realty firm owned by the Agarwals, the grandfather of the minor, who is one of the owners of the firm, was questioned in regards to the ownership of the car," an officer said.
