Mumbai, May 25 (IANS): In a sensational daylight robbery, at least three armed people barged into Air India's cargo complex adjacent to the domestic airport here and escaped with 145 kg of gold and silver coins worth millions of rupees, officials said.

The criminals armed with guns and revolvers barged into the high security zone at about 11.30 a.m. and attacked security guard S. Bhosle when he attempted to stop them, an Air India spokesperson said.

At that time, some officials of Messrs Pidilite Industries were booking six packets of gold and silver coins, weighing 145 kg in all, at the cargo complex. The consignment was bound for Hyderabad.

A police official said the company officials were in the process of screening the packets when the armed robbers barged in, threatened the security personnel and fled with four packets.

They got into a car and disappeared from the scene of the crime within minutes.

"We have put up road blocks all over the city and alerted security staff at all exit points to be on the lookout for the culprits," the police official said.

According to the Air India spokesperson, the injured security guard was admitted to a nearby hospital.
