The incident took place around 10.30 PM last night when Vijay Kumar Wadhwa, was heading home in Kewal Park area after closing his garment shop.
When he reached Majlis Park area on his scooter, two motorcycle-borne persons approached him and after pulling out a gun, asked him to hand over his bag, a senior police official said.
As Wadhwa kept resisting, the assailants opened fire and a bullet hit Wadhwa on his head, police said.
When the robbers realised a passer-by had witnessed the incident, they shot at his car too. But the bullet hit his car's window and the man sustained injury from the shattered glass.

Wadhwa was rushed to a hospital where doctors declared him dead, following which a case of murder was registered. Efforts are on to track down the accused at the earliest, the official said.
The bag, which the robbers were trying to rob, however, contained no cash. It only had the keys of his shop and some important documents.
It can't be ruled out at this stage that the robbers followed Wadhwa's movements before they decided to execute their plans yesterday, the official said.
