New Delhi, May 1 -- Hours after a man rammed his car into a stationary motorcycle at a petrol pump in Najafgarh on the night of April 13, breaking bottles of beer being carried on the bike, the two became unlikely companions and shared drinks. But what ensued eventually between the drunk men was a fight over the incident - when the victim asked for compensation, the driver of the SUV hit him with a brick, killing him on the spot, transported his body in his car for two kilometres and dumped it in the Bakkarwala drain, according to the version of events shared by the police. Rohit Singh, 28, a BBA graduate who works as a cashier with a private bank, was arrested, police said on Wednesday. The victim was identified as 40-year-old Jagvinder Singhania who worked at a grocery shop in RK Puram. "As per Singh's statement, the altercation between him and Singhania ensued again at an isolated place in Nirmal Vihar. Despite drinking the beer purchased by him, Singhania demanded cash as compensation for the damaged beer bottles. Both were inebriated at that time. During the scuffle, Singh picked up a brick and attacked Singhania, killing him on the spot," joint commissioner of police (western range) Jatin Narwal said. Police said that immediately after the collision, which took place around 11pm, Singh ferried Singhania in his Scorpio car and bought beers to consume with him. Singhania parked his TVS Apache motorcycle in Najafgarh, and got into Singh's car. Police said that Singh panicked when Singhania died, around 12.30am on April 14. He bundled the victim's body in his car, stopped his vehicle at an isolated place near the Bakkarwala drain, pulled out his body, dragged it and threw it into the drain along with the brick used in the crime. "The CCTV cameras of the onward routes were scanned, and investigators zeroed in on three black Scorpios. While investigation into Singhania's missing complaint was on, a highly decomposed body was recovered from Bakkarwala drain on Sunday. Singhania's family members were shown the body, and they identified him by his clothes," a senior police officer said on condition of anonymity. The probe eventually led to the identification of the Scorpio and its owner, Rohit Singh, was arrested on Tuesday, they said....
