The CBI hand-delivered a summons to TMC MP Abhishek Banerjee for questioning in connection with the teachers' recruitment scam case on Monday, allegedly over two hours after the Supreme Court had stayed a high court order for his interrogation.
An agency official said the notice was prepared on Sunday and delivered on Monday.
Meanwhile, Trinamool Congress MLA Jiban Krishna Saha was arrested on Monday by the CBI from his residence in West Bengal's Murshidabad district in connection with its investigation into the school jobs-for-bribes scam, officials said.
Saha, an MLA from the Burwan constituency, was being questioned by the CBI since April 14 in connection with the case as searches went on at his house in connection with the illegal recruitments in state-sponsored and aided schools, they said.
