Mohali/Chandigarh, Sept. 26 -- A 36-year-old gym owner was injured after two masked motorcycle-borne youths opened fire at a gym in Mohali's Phase 2 and, within an hour, at a hotel in Chandigarh's Kajheri on early Thursday. Acting swiftly, Chandigarh Police's operation cell arrested the accused, one of them a murder convict, within 10 hours of the brazen incident. The accused were identified as Ritvik Bhardwaj, alias Billa, and Aman, both residents of Burail village, Chandigarh. In November 2021, Bhardwaj, along with three others, was convicted of the 2019 murder of a 27-year-old youth in Sector 40 and awarded life imprisonment by a local court. He is currently out on parole. Police said the Thursday attack was retaliation for a long-running feud in the victim's neighbourhood. Around 4.55 am, Vicky, a resident of Sector 49, drove his Maruti Suzuki Baleno into the parking lot outside his gym "Muscle Mania" on Franco Road, Phase 2, Mohali. The accused, riding a sports bike followed the car, circled the area twice and then opened fire at Vicky. The assailants fired five bullets within roughly a minute, four of which struck Vicky's right leg near the thigh. A gym trainer alerted Vicky's brother, and he was rushed on a bike to the civil hospital in Phase 6. After about four hours of treatment, doctors referred him to PGIMER, Chandigarh, where he underwent surgery. Hospital sources said his condition is stable and out of danger. Shortly after the Mohali shooting, the same duo opened fire at Hotel Diljot Residency in Kajheri, run by Vicky's friend Veeru. The accused discharged around five rounds, shattering glass panels and sending staff and guests scurrying for cover. Veeru's brother-in-law, Bhagat, who was present at the hotel counter, hid behind the stairs to protect himself. No injuries were reported at the hotel. Around 5 am, police received the first reports of gunfire and rushed teams to both locations. Vicky's brother Banti told investigators that their family was being repeatedly threatened by their neighbours over old disputes. Banti alleged that their neighbours, named Vikas and Suraj, both currently lodged in Model Jail, Chandigarh, had been issuing threats and orchestrated the Thursday attack from behind the bars. Later in the day, a video surfaced on Instagram, with Ritvik and Aman, claiming to be brothers, taking responsibility for both the Mohali and Chandigarh firings. In the video they accused the owners of the Mohali gym and the Chandigarh hotel of promoting drug sales and running prostitution rackets, saying such activities were "spoiling the environment" of both cities. In another post, they accused Vicky of inappropriate behaviour and illegal business dealings. However, police have not verified the authenticity of the video....
