The AAP terms the arrest “motivated and an act of political vendetta”.

Delhi Chief Minister Arvind Kejriwal’s nephew Vinay Bansal was arrested by the Delhi's Anti-Corruption Branch (ACB) on Thursday for his involvement in an alleged scam relating to the construction of drains by the Public Works Department (PWD), sources in the anti-graft body said.

The ACB filed three FIRs in connection with the scam exactly a year ago against Renu Constructions and named Mr. Vinay Bansal’s father Surender Bansal and others involved in the company’s operations.

Surender Bansal passed away soon after he was named in an FIR.

According to sources in the Aam Aadmi Party (AAP), Mr. Vinay Bansal was picked up from his residence in Pitampura, north-west Delhi, around 4 a.m.

The FIRs were registered on the basis of a complaint by Rahul Sharma, founder of NGO Roads Anti-Corruption Organisation (RACO). It alleged irregularities in the grant of contracts for roads and sewer lines in 2015-16.

The AAP termed the arrest “motivated and an act of political vendetta.” Mr. Vinay Bansal was a dormant partner in the company that is being investigated by the ACB, it said, adding that the ACB was being used to malign the image of Mr. Kejriwal.
