Gurugram, Nov. 10 -- Police recovered a pistol suspected to have been used to kill Singapore-based executive Paramjith Dhankhar, 43, from Punjab's Patiala district on Monday night and are investigating whether the accused possessed an unregistered firearm, officials said. The pistol and a magazine containing six live cartridges were recovered from Samana following information provided by accused Mohan Sharma, 42, during questioning. Dhankhar was shot dead on Friday night in the stilt parking area of his residential building in Faridabad's Sector 21C following a three-month dispute over Sharma's puppy allegedly defecating in the common area. A senior police officer said Sharma told investigators that the pistol recovered from the crime scene was not the murder weapon. After the shooting, Sharma allegedly drove to Patiala, disposed of the weapon and returned to Faridabad, where he was arrested at Dealer Chowk in Ballabgarh Saturday. Police will send the recovered pistol, 15 spent cartridges found at the scene and bullets retrieved during Dhankhar's autopsy for forensic examination and ballistic matching. "The other pistol recovered from the spot, which was found in a weapon casing with a loaded magazine and 59 live rounds, will also be sent for ballistic testing to ascertain Sharma was not lying," the officer said. Two additional magazines, which police suspect were emptied during the shooting, were also found at the scene. Records show Sharma received an arms licence in December 2023, with a pistol and a 12-bore gun registered against it. Police are investigating how he acquired another pistol, which does not appear in the licence database, and whether he possessed it illegally. Investigators are also reviewing why Sharma was granted the licence. Police said he ran a copper scrap business in Rajasthan and worked in real estate in Faridabad. The licence was issued following an assessment of threats to his safety. "We are checking the records to establish on what grounds he was issued the licence, for which cancellation proceedings have already been started," an officer said. Dhankhar, formerly Tech Mahindra's Asia-Pacific business head and later a senior vice-president at Vietnam-based FPT Software, returned from Singapore on November 5 for Diwali and a nephew's wedding scheduled for November 24. Police said Sharma had damaged an entrance gate installed by Dhankhar about 10 days before the killing. On Friday, both men were summoned to the Ankhir police post following Dhankhar's complaint. Sharma allegedly misbehaved with officers and threatened him. That night, Sharma allegedly summoned Dhankhar downstairs on the pretext of moving a car and opened fire when he arrived with his son Shaurya. At least nine bullets struck Dhankhar, police said. Shaurya escaped by hiding behind a vehicle. Faridabad police spokesperson Yashpal Yadav said Sharma's two-day police remand, granted on Sunday, would end Tuesday....
