Thiruvananthapuram: The National Investigation Agency (NIA) will again interrogate M Sivasankar, former principal secretary to Chief Minister in connection with the gold smuggling case. The NIA has issued a notice summoning him to appear at the Kochi office of the agency on Monday.
On Thursday, the NIA questioned him for more than five hours.
The NIA is investigating whether the accused had visited Sivasankar at his office before the gold was seized. However, he had denied any involvement in the smuggling and said that he only had a friendship with Swapna Suresh and Sarith, the two accused.
At the same time, NIA has demanded for CCTV footage from the secretariat from July 1 to 12.
Also, Sivasankar has started procedures for seeking anticipatory bail fearing the arrest.
