- Pankaj Narang was beaten to death with rods and sticks
- He had an argument with two motorcyclists minutes earlier

Mr Narang fell to the ground and hit his head against the road, but the men did not stop, hitting him repeatedly on the head.
The police said today that it has arrested five people and apprehended four minors for Mr Narang's murder. Among those arrested is the mother of Naseer, a 23-year-old man with whom Mr Narang had an altercation less than an hour before he died
The police said at a little after midnight, Dr Narang was playing cricket in his home with his son and nephew, celebrating India's one-run victory over Bangladesh in the World Twenty20 tournament.
The ball bounced out on to the road and the dentist's eight-year-old son ran out to retrieve it. Just then, the police said, Naseer and one of the minors arrested were speeding past on a motorbike, which grazed the child. Dr Narang flagged them down and a heated argument followed.
Naseer then drove off, the police said, only to return about 10 minutes later with 10 people and they attacked Dr Narang. Witnesses said people who had gathered attempted to intervene, but they were thrashed too. Dr Narang died on the way to hospital.
The police said today that all the accused live in a slum just behind the dentist's home and do casual jobs at a local market. While the men arrested are in their early twenties, the minors are between 17 and 18 years in age.
A case of murder, attempt to murder, trespassing and rioting has been registered.
