Kolkata, Apr 12 (IANS): The CBI on Monday interrogated the alleged coal scam kingpin Anup Majhi alias Lala for the sixth time.

According to the probe body, Majhi appeared before the CBI at around 11 a.m.

A CBI official said that he was being questioned in connection with the scam and about his financial dealings and his properties in the state (West Bengal).

The investigation agency had earlier grilled Majhi for several hours on April 1, 6, 8 and 10, and on March 30 in connection with the scam.

The CBI has also summoned Bankura Superintendent of Police Koteswara Rao N on April 13 for questioning in connection with the illegal coal smuggling case.

Majhi's close aide Ganesh Bavaria was questioned on April 3, and Birbhum's former Superintendent of Police Shyam Singh on April 1. Besides, former Asanol Commissioner Laxmi Narayan Meena was also interrogated.

On April 5, the Enforcement Directorate, which is probing the money laundering part, attached Majhi's immovable assets to the tune of Rs 165.86 crore.

They include land, factory premises, plant machinery and other assets of two companies -- Ispat Damodar Private Ltd and Sonic Thermal Private Ltd.

The manufacturing plants of both these companies are situated in West Bengal's Purulia and Bankura.

Majhi, the Director of a company engaged in the purchase and sale of dry fuel, is accused of alleged illegal coal trading in the Asansol-Raniganj belt of West Bengal.

The CBI had registered a case involving alleged illegal coal pilferage in November last year, naming Majhi, Eastern Coalfield Ltd General Managers Amit Kumar Dhar and Jayesh Chandra Rai, ECL chief of security Tan Das, area security inspector Kunustoria Dhananjay Rai, and SSI and security in-charge Kajora area Debashish Mukherjee.

It had also recorded the statement of Rujira Banerjee, wife of Trinamool Congress MP and Chief Minister Mamata Banerjee's nephew Abhishek Banerjee and his sister-in-law Menka Gambhir in the last week of February.

The agency has recently carried out searches at several locations in the state, including at the premises of Amit Agarwal, a close aide of Majhi, raising the heat in poll-bound West Bengal, where the ruling Trinamool Congress and the BJP are engaged in a pitched battle.
