Port-of-Spain, Jun 11 (IANS): An Indian bank here was targeted by four robbers who tied up three Indian employees and demanded keys to the vault. Policemen who were passing by noticed the heist and nabbed them.

The four people charged with the robbery in the Bank of Baroda branch will appear before a Port-of-Spain Magistrate Court Monday.

Top officials, including the country's National Security Minister Brig. John Sandy and Chief of Defence Staff Kenrick Maharaj, as well as Indian High Commissioner to Trinidad and Tobago Malay Mishra visited the bank.

Bank of Baroda opened its first branch in the city in 2007.
