He added: “Our investigation clearly shows that the juvenile accused was driving the car. We have collected all the evidence chronologically to prove it.”

Speaking about the blood test to measure alcohol content, he added, “The report of a test conducted to measure alcohol content in the blood of the minor boy is not important for the investigation in the case.”

The two IT engineers were killed after the speeding Porsche driven by a 17-and-a-half-year-old boy in an inebriated state hit their motorcycle.

The police commissioner had said on Thursday that it cannot be said the minor boy committed the offence under the influence of alcohol. “In spite or despite of the blood report, our case is that he (minor boy) was in full senses and was having knowledge that his act of consuming liquor and then driving a car at high speed in a narrow lane can cause deaths of people,” Kumar had said.

While there are allegations that the police caused a delay in the collection of the minor boy’s blood samples, Kumar told reporters, “We have not received the blood report yet. But I repeat that the blood report is not important for us.”

The police claim to have evidence of liquor consumption against the minor boy, which includes CCTV footage and bills from two restaurants where the minor boy, son of a prominent realtor, had been allegedly drinking with his friends before the accident.
