A man's rotting body was found on the protected tunnel of Delhi Metro's airport lane. According to the police, the man had died at least four to five months ago and only his bones were found. The death left the police in confusion, as it is nearly impossible to go inside the tunnels. Reportedly, the death has been narrowed down to three reasons - murder, theft and inside involvement. The Delhi police are stumped as the tracks are barred with security gates and CCTVs there do not carry footage for more than 30 days.
