Former Mumbai NCB chief Sameer Wankhede was questioned for more than five hours on the second day in a row on Sunday by CBI probing the alleged Rs 25 crore bribe demand from actor Shah Rukh Khan for not implicating his son Aryan in the Cordelia cruise 'drug bust' case, an official said.

Wankhede, an Indian Revenue Service (IRS) officer, reached the Central Bureau of Investigation's (CBI) office in the Bandra-Kurla Complex at around 10.30 am, he said.
