The deceased, identified as Dinesh, was a supplier of construction material and lived in Jahangirpuri. The four bike-borne assailants came to his shop this morning and allegedly shot him dead, said a police official.
The assailants fled the spot once Dinesh collapsed on the floor, following which locals rushed to his shop and informed the police.
Dinesh was rushed to a hospital, where he was declared dead on arrival, the official said adding that it so far appears to be a case of personal rivalry.
