India, Nov. 11 -- A court on Tuesday extended by three days the police custody of Mohan Sharma, accused of shooting dead his neighbour, Singapore-based executive Paramjith Dhankhar, as investigators sought to recover the car allegedly used to flee the scene and examine the possible involvement of his relatives. Sharma was arrested at Dealer Chowk in Ballabgarh on Saturday, a day after Dhankhar, 43, was killed in the stilt parking area of a building in Sector 21C. He was remanded in police custody for two days on Sunday, and police sought an extension when that remand ended. Investigators said a crime branch team recovered a .30-bore pistol and a magazine containing six cartridges from Samana in Punjab's Patiala district on Monday, based on information provided by Sharma during questioning. A .45-bore pistol had been recovered from the crime scene. Both weapons have been sent for forensic examination, police said. A senior officer said investigators were still searching for the car Sharma allegedly used to escape after calling Dhankhar downstairs on the pretext of asking him to move his vehicle. Police were also questioning Sharma about whether his wife, two children and brother, named as co-accused, knew of any plan to kill Dhankhar. Investigators said the families had been locked in a dispute for about three months over Sharma allegedly allowing his German Shepherd puppy to defecate in the shared parking area. Dhankhar's family had repeatedly objected, they said. Police spokesperson Yashpal Sharma said investigators were checking whether both pistols were registered against the accused's arms licence....
