Birbhum: Diamonds, gold worth Rs 5 crore stolen from store

“The burglars also destroyed CCTV cameras installed and took the computer hard disk with them,” said D Jana, owner of the showroom.

Sources said police are probing whether an insider was involved, adding that at the time the theft took place, two security guards were on duty on the ground floor.

Investigators also suspect that four people, who had been living in a lodge close to the store, could be the culprits as they had checked out just before the crime was committed. Lodge manager Kalinath Dey has been interrogated in this regard.

“We are investigating, it was a well-planned operation”, said a police officer. Police have also informed the CID, seeking their help in nabbing the culprits.
