Former Maharashtra Home Minister Anil Deshmukh has been summoned by the Central Bureau of Investigation on April 14 in connection with the extortion allegations levelled by former Mumbai Police Commissioner Param Bir Singh. 

The summon from the CBI comes a day after the agency quizzed two of Deshmukh's aides Sanjeev Palande and Kundan.

Param Bir Singh has alleged that Deshmukh called suspended Assistant Police Inspector Sachin Vaze and told him to extort Rs 100 crore a month from restaurants, pubs and other establishments in Mumbai.

He also alleged that Deshmukh was in touch with other officers for the same. The former top cop's serious allegations of malpractices had prompted the Bombay High Court to order a preliminary CBI probe against the former Maharashtra Home Minister.

The CBI has recorded the statements of Param Bir Singh, Vaze, ACP Sanjay Patil and complainant Jaishri Patil. 

The agency has also quizzed bar owner Mahesh Shetty who visited the Crime Intelligence Unit office on March 3 where he allegedly saw late businessman Mansukh Hiren and convicted police officer Vinayak Shinde.
