A jewelry showroom in south Delhi was robbed of over 30kg of gold and other jewelry, as well as Rs 5 lakh in cash, in a unique heist. The thieves entered through the terrace, crossed over from an adjacent building, and drilled a hole in the concrete wall of the strongroom. The alarm system had been disabled, and CCTV cameras were rendered non-functional. The police are investigating the incident and suspect a possible insider involvement. Over 20 teams comprising 200 cops have been deployed to crack the case.
