A team of CBI officers turned up at the residence of Trinamul Congress MP Abhishek Banerjee here on Sunday and served a notice on his wife Rujira asking her to attend a questioning session as a witness in connection with the agency’s ongoing probe into alleged pilferage of coal worth thousands of crores of rupees across Bengal.

The notice asked Rujira to participate in the questioning session at her Harish Mukherjee Road residence.

“We would want to question her as a witness and she has been asked to attend the questioning session under Section 160 of the CrPC,” said a senior CBI officer.

Section 160 of the Code of Criminal Procedure relates to the power of a police officer to issue orders in writing looking for attendance of any person whom he believes to be acquainted with the facts and circumstances of the case that he/she is probing into. The section spells out that no woman shall be required to attend this questioning session at any place other than where she resides.

A special court for MPs and MLAs here had on Friday issued summons to Union home minister Amit Shah to appear before it either personally or through a representative on February 22 in a defamation suit filed by Abhishek, the nephew of chief minister Mamata Banerjee.

On Sunday, Abhishek said he had full faith in the law of land.

Without referring to the CBI notice, Mamata said she was not afraid of anybody and would not be silenced with attempted intimidation. “Do not ever try to intimidate us with jail. We were raised fighting guns and state-sponsored atrocities, and are not afraid of fighting rodents.”
