PATNA, Oct. 22 -- A 19-year-old son of a Bharatiya Janata Party (BJP) district leader was shot dead by four unidentified assailants in Bihar's Gaya district on Monday morning. A CCTV video clip of the incident has gone viral on social media, police said. The incident took place in the Murli Bairagi locality under the jurisdiction of Kotwali police station. The victim, identified as Subhash Kumar (19), was the son of BJP leader Upendra Paswan, former SC/ST wing president of the Gaya BJP unit. Eyewitnesses said the attackers fled the spot brandishing their weapons, while bystanders looked on without intervening. Police suspect the murder was linked to a five-year-old dispute. The viral CCTV footage is being examined to identify and arrest the culprits. According to Gaya City Superintendent of Police (SP) Ramanand Kaushal, Subhash was allegedly shot dead by acquaintances. "An FIR has been registered and a probe is underway. We are identifying the suspects, and action will be taken as per law," Kaushal said. The SP added that three of the four assailants fired four bullets at Subhash from close range, killing him on the spot. CCTV footage shows Subhash standing with four youths, holding a stick. One of them suddenly draws a pistol and points it at him. Subhash appears unfazed, possibly assuming the youth wouldn't shoot. Moments later, he is shot and collapses. Even after being hit, Subhash is seen trying to speak to the attackers before being shot again. Another youth then steps forward and fires at his chest and head from close range. The video shows Subhash writhing in pain as the assailants calmly walk away, brandishing their weapons. Several people witnessed the incident, but none intervened or called the police. "My son had gone out in the morning for some work. The criminals were already waiting for him. They shot him from point-blank range. This was a planned murder-someone hired contract killers to eliminate my son," said Upendra Paswan....
