The central probe agency's letter was dispatched a day after it had sent a notice to the TMC MP asking him to appear before its sleuths at its Kolkata office for questioning in connection with the school jobs scam following certain allegations of arrested Trinamool Congress youth leader Kuntal Ghosh.
Dehadrai, who was once close to Moitra, had levelled serious corruption allegations against the former MP which were strongly refuted by her, they said.
However, there was no official word from the Lokpal.
A team of Central Bureau of Investigation (CBI) officials, led by the agency's Special Director Ajay Bhatnagar, will reach Imphal in a special flight on Wednesday to investigate the 'kidnapping and killing' of two students who went missing in the northeastern state on July 6, sources said.
