Agartala, Oct 13 (IANS): Tripura Police Monday raided the residence of a civil service official here and seized some documents related to a multi-crore scam, police said.

Auditors found financial wrongdoing to the tune of Rs.17 crore at Bishalgarh block in Sipahijala district a few months back, triggering a political storm against the Left Front government, which has a clean image on the corruption issue.

"We have raided the residence of a civil service officer at Milanchakra on the outskirts of the city and seized some documents," additional superintendent of police Sharmistha Chakraborty told reporters.

She said: "Incumbent BDO (block development officer) of the Bishalgarh block lodged an FIR (first information report) Sep 19 against 12 officials, including the civil service officer and several engineers."

The state government has asked all the 12 officials to report to police by Oct 14 to share information about the scam and assist the authorities to conduct the probe into the misuse of central government funds.

The opposition parties, including the main opposition Congress and the Bharatiya Janata Party, demanded a CBI (Central Bureau of Investigation) probe into all the scams unearthed during the Left Front rule in the state.
