The thieves disconnected CCTV cameras and made a hole in the strongroom wall. They entered from the terrace of the four-floor building and reached the ground floor where the strongroom was located, officials said. Apart from stealing the ornaments kept in the strongroom, they also escaped with the jewellery kept on display at the showroom.

The showroom was locked on Sunday evening and opened only on Tuesday morning since it remains shut on Mondays. The cops are going through whatever was recorded on CCTV before the thieves disconnected them. No one has been arrested yet, NDTV reported.
