Agra, July 28 - Burglars broke into the house of a jeweller here early Tuesday morning and escaped with five quintals of silver, worth Rs.one crore, as the family members slept on unaware in their rooms, police said.

Two armed guards at the colony were also sleeping at the time, according to the residents.

The jeweller, Rajvir Singh, a resident of Khandelwal Colony in Vijay Nagar area, runs a factory in his house, producing silverware, bracelets and also carrying out job work for others. Police suspect an employee or an ex-employee of Singh could be involved in the crime.

Police sources said Singh and his family members were asleep in their rooms when the burglars entered the premises and fled with the bullion, leaving no traces for sniffer dogs and fingerprint experts.

Two suspects have been taken into custody for interrogation, police said. Superintendent of Police (city) B.P. Ashok told media persons it could be the handiwork of 'somebody working or an ex-employee acquainted with the geography of the area and the house.'
