A Pune court has extended the police custody of Sia Goel and Chetan Choudhury until July 3 as investigators probe the murder of 25-year-old Ketan Agarwal. Police allege the accused used a pre-planned hand signal to execute the crime, researched murder methods online, and attempted to destroy evidence after the incident. Investigators are now examining digital records, CCTV footage, call data and forensic evidence to reconstruct the sequence of events and establish how the alleged murder was carried out.
