Subrat, the son of drug trader Vineet Minocha, was arrested following his alleged involvement in his father's murder. Investigators based their actions on the statement of Vishal Gautam, who claimed Subrat offered him money for the crime. Shalu, Subrat's wife, was implicated as well, with evidence suggesting she aided the murderers. Police discovered a blood-stained cloth linked to the incident during their investigation in Ratan Orbit.
