The CBI on Sunday began its second round of questioning of Deputy Chief Minister Manish Sisodia in connection with the Delhi excise policy scam case. Sisodia arrived at the heavily-barricaded CBI office after paying homage to Mahatma Gandhi at Raj Ghat, officials said.

Sisodia, accused number one in the CBI FIR, was earlier questioned on October 17, a month before the agency filed its charge sheet on November 25 last year.
