Samajwadi Party leader Amar Singh, 53, filed a general diary against Uttar Pradesh Chief Minister Mayawati, 53, and six others at Ballygunge police Station in Kolkata on Friday afternoon complaining that she has hatched criminal conspiracy against him and his associates including filmstar Amitabh Bachchan.
Apart from Mayawati, the people named in the complaint are Shiv Kanta Tripathi, Navneet Saigal, Baburam Kushwaha, Akhilesh Das, Dinesh Tripathi, Shivkanth Tripathi.
Amar Singh met the Kolkata police commissioner and requested him to treat the complaint as a first information report.
Singh also distributed a CD to media persons, which, he alleged, contains proof of corruption and conspiracy by the people named in Friday's complaint.
On 15 October, an FIR was filed at Babupurwa police station in Kanpur alleging Amar Singh, Amitabh Bachhan and others under different sections of the Indian Penal Code and Prevention of Corruption Act and Money Laundering Act.
Amar Singh's wife Pankaja Singh and friend filmstar Amitabh Bachhan had also been named in the FIR.
Shivkant Tripathi, who has been named by Amar Singh in his complaint to the police in Kolkata, had lodged the FIR in Kanpur.
"My permanent address is in Kolkata. I have retained my company headquarters in Kolkata. I also file my income tax returns in Kolkata," said Amar Singh explaining why he lodged the complaint in this city.
The FIR in Kanpur had alleged Samajwadi Party general secretary Amar Singh misused his position and siphoned off public money during the tenure of the previous Mulayam Singh Yadav government in Uttar Pradesh.
The FIR was lodged by one Shiv Kumar Tiwari in which he stated that Singh, who was chairman of Uttar Pradesh State Development Council during Mulayam Singh Yadav's tenure, collected money for setting up industries and later squandered the money.
''It is a fraud committed in the name of public of this state,'' Tiwari said in his FIR lodged with Babupurwa police station in New Labour Colony.
In the four-page FIR, Tiwari said Singh and filmstar Amitabh Bachchan had worked in tandem to squander the money.
