Gurugram, June 6 -- A drunk 36-year-old man was arrested for shooting dead a 23-year-old man on the premises of ILD mall on Sohna Road in Gurugram Sector 47 in the early hours of Thursday, police said. The victim was identified as Wasim Khan, a resident of Gairatpur Bas in Sohna and worked as a contractor. The accused was identified as Deepak Kumar, police said. The incident was the fallout of an argument between the victim and his colleagues, who were contractors working at the mall, and an associate of the accused who operates a paan shop near the mall entrance, police said. "A man named Manoj Kumar, who runs a paan shop outside the mall, got drunk on Wednesday night and picked a fight with a man named Niranjan (single name), a contractor who was carrying out construction and demolition work inside the mall. Khan was also a contractor working with Niranjan. He was killed by Kumar, an associate of Manoj Kumar, the paan shop owner," said inspector Sunil Kumar, station house officer of Gurugram Sadar police station. The incident took place between 1.15am and 1.20am when Khan arrived at the mall with his elder brother Sehwag and other workers to lift the construction and demolition debris. Police arrested Kumar on Thursday evening. "Manoj Kumar and four of his associates are on the run," he added. Based on Sehwag Khan's complaint, a first information report (FIR) was registered against the accused under sections 103(2) (murder) and 61(criminal conspiracy) of the Bharatiya Nyaya Sanhita and the Arms Act at Gurugram Sadar police station....
