Police sources said half a dozen persons came menacingly in the city’s Chordi Darwaza area in a black SUV without any registration number and opened indiscriminate fire, injuring one person of another community.
The person sustained bullet wounds in the throat and leg and was shifted to a government hospital in Gondal, 40 km from Rajkot. The incident took place on Thursday night.
The police said this provoked the other community to retaliate. Soon, a mob of over 100 people came together in a jeep and motorcycles armed with weapons.
The irate mob attacked a vegetable shop owner in the Old Market Yard of the city who was passing by. The man died on the spot.
Acting swiftly, the police chased the black SUV, intercepted it and arrested its five occupants. A search is on for two more persons, a police officer said.
