At least two people, including a woman, suffered bullet injuries when two groups fired upon each other in southwest Delhi’s Uttam Nagar. The incident happened on Wednesday night around 10.30pm when argument started between two neighbours allegedly over commercial properties in the area. The cops are probing if the fight had actually triggered over the control of illegal gambling in the area by the two rival groups. Both Akram and Yamin had bought commercial properties in the same lane.
