Reacting to CBI's action against AAP minister, Chief Minister Arvind Kejriwal tweeted: "Prime Minister Narendra Modi has done this case against Satyendra Jain because he was working on a scheme to regularise unauthorised colonies. People who live in unauthorised colonies will respond to this allegation".

The CBI in its chargesheet has alleged that Jain has amassed disproportionate assets of approximnately Rs 1,47 crore.

The chargesheet, filed before a Delhi Court, named Jain, his wife Poonam Jain and business associates Ajit Prasad Jain, Vaibhav Jain, Sunil Kumar Jain and Ankush Jain.

They have been chargesheeted under Section 109 (punishment of abetment) of Indian Penal Code with the provisions of Prevention of Corruption Act.

The Union Home Ministry on Thursday granted sanction to prosecute Satyendar Jain in the disproportionate assets case.

Jain is accused of floating several shell companies in Delhi including Akinchan Developers Pvt Ltd, Indo Metal Impex Pvt Ltd, Paryas Infosolutions Pvt Ltd and Manglayatan Projects Pvt Ltd during 2009-10 and 2010-11 for alleged money laundering.

"These shell companies do not have any real business. Satyendar Jain had laundered black money of Rs 16.39 crore during 2010-11 to 2015-16 through 54 shell companies of three hawala entry operators of Kolkata -- Jeevendra Mishra, Abhishek Chokhani and Rajendra Bansal," said an official in the Home Ministry.

Jain, who holds seven portfolios including Health, Home and Public Works Department, has denied the allegations, saying the CBI action is politically motivated.

The CBI initiated a probe in April 2017 and registered an FIR on August 24 this year.

The agency alleged that Jain and his family members allegedly controlled or have stake holding in the four companies based at Delhi.

He was Director in three companies and resigned from the directorship of these three companies before the election in 2013. His family members, however, continued to hold shares in all these four companies.

Jain exercised effective control in these companies through his wife, the CBI said.
