New Delhi, Jul 3 (IANS): At least five persons sustained bullet injuries in the national capital after gunmen opened fire in three separate incidents within 24 hours. One of the victims succumbed to the injuries while four are still battling for life in various hospitals.

In the first incident, two sisters were shot by two boys in South West Delhi's Kapashera on Thursday evening. The two girls aged 15 and 13 received bullet injuries in the stomach and leg respectively. One of the boys was annoyed after the girl's family allegedly scrapped the engagement with him. It was then that he decided to barge into the house of the girl with his friend and shoot her. Both have been nabbed and the two girls are battling for life in a hospital.

The second incident was reported from Delhi's Rohini where in an alleged case of mistaken identity gunmen shot dead the son of a retired Delhi police ASI on Thursday night. The deceased was identified as Nitin Dalal.

"Nitin Dalal, son of a retired Delhi police Assistant Sub Inspector was shot dead by some unknown persons. They came in a Santro car. Nitin was driving his brother's car when he was attacked. Neeraj, elder brother of Nitin, is in the property business." said DCP Rohini PK Mishra.

Since Nitin was driving his brother's car the police suspect it might be a case of mistaken identity where the gunmen mistook Nitin for his brother Neeraj.

In the third case of shooting reported on Friday morning, three to four men entered B Block of Nand Nagri in North East Delhi at around 11.45 a.m. and fired at a 42 year old businessman who has been identified as Naresh. Another man Pramod who was also standing in the lane received a bullet injury in the firing. Both are admitted in a hospital.
