New Delhi: A long-running rivalry in south Delhi’s Fatehpur Beri has taken another turn with police arresting a key conspirator nearly a year after dairy businessman Ratan Lohia was gunned down in a barrage of nearly 70 rounds.The accused has been identified as Rambir Lohia, 52, a resident of Fatehpur Beri and the father of businessman Arun Lohia, who was allegedly shot dead by Ratan’s son, Deepak, in May last year.Police sources said investigators recovered footage showing Rambir and his relative Kamal sitting with the shooters before Ratan’s murder. The footage was sent to Forensic Science Laboratory (FSL), which, according to police, confirmed that it had not been tampered with and predated the murder.Officers also gathered other evidence against Rambir, which eventually led to his arrest, sources said.According to police, the rivalry, which stems from a dispute over a plot of land, has now claimed three lives.The feud began escalating in 2024 when Ratan’s son, Deepak, was allegedly attacked in connection with the longstanding property dispute. An attempted murder case was subsequently registered against 24-year-old businessman Arun, who was named as the prime suspect.The conflict turned deadly in May 2025 when Deepak and his associates allegedly opened fire on an SUV near Chhatarpur metro station. Arun, who was returning home with his father Rambir, was killed in the firing.Police subsequently arrested three people, including Deepak and Ajay, in connection with the murder.Months later, the violence returned to the Lohia family. On Nov 30, Ratan was shot dead near his home while he was on his way to his dairy in Aya Nagar. His family alleged that nearly 70 rounds had been fired at him. Cops later arrested a known associate of Arun, along with other suspects, in connection with the murder.The latest killing in the chain took place on Sept 14, when Vijay, Ajay’s brother, was shot dead near Hansa Chowk.According to police, the incident took place around 10am. After allegedly confirming Vijay’s movements, the shooters opened fire on him outside his gym.Following raids at several locations across Delhi-NCR, police arrested Deepak in connection with Vijay’s murder. He was arrested for harbouring the shooters.With Rambir’s arrest, investigators are now examining the wider conspiracy and the links between the successive killings as the rivalry between the two sides continues to unfold through multiple murder cases.
