During scrutiny of CCTV footage from the foothills, we noticed a person wearing a hoodie with his head covered and also wearing headphones. This raised suspicion because such clothing was unusual considering the weather conditions,” senior police inspector Dinesh Tayade of Lonavala Rural Police told HT.Police also revealed that Chaudhary also attempted to avoid detection by leaving his mobile phone at his Kondhwa residence rather than carrying it to the fort.Investigators tracked CCTV footage and subsequently questioned both Chaudhary and Siya. During the interrogation, the two allegedly confessed to the crime, police said. The duo has been sent to police custody for seven days.
