Police investigating the alleged murder of Ketan Agarwal at Maharashtra's Lohagarh Fort claim the accused, Chetan Choudhury, meticulously planned a digital cover-up by staying offline for over 10 hours, leaving his phone behind and using a borrowed handset. Investigators say CCTV footage, witness statements and the prolonged digital silence ultimately exposed the alleged plan, turning the accused's attempt to erase his trail into crucial evidence.
