Four persons including a juvenile, have been apprehended for allegedly shooting a man dead outside V3S mall in east Delhi's Preet Vihar last month, the city police said on Friday.

Nishant Arora, Nimit, Sameer and their juvenile accomplice were arrested on Thursday night.

"They on March 24 shot Vishal outside a mall in Preet Vihar area. Nishant killed Vishal over a personal animosity that arose due to gambling business," Deputy Commissioner of Police Omvir Singh said.

Vishal along with his accomplice went to Nishant's residence and threatened him with dire consequences on the intervening night of March 23-24, Singh said.

Later on, Nishant and his gang members followed Vishal and his associates and fired on them when they were looking for food near V3S Mall in Preet Vihar, the police officer said.
