"The footage from the CCTV cameras along the route used by the accused persons was examined. A search was conducted at the last place where they stopped, Ram Dutt Enclave in Uttam Nagar, and they were arrested," Alphonse said.
The accused are Pawan (22), Vishal (23), Parveen (22) and Kishan (23). Three pistols along with 13 cartridges were seized from them, police said.
"The four men used to fire from their vehicle at random things at night for target practice. On August 29, around 3:30 am, they shot at Sunny just for target practice. They first fired in the air and then at Sunny, who suffered a bullet injury in his stomach," he said.
