Speaking to reporters in New Delhi, Buta Singh denied all charges against him.

Along with Sweety Singh, three men -- Anoop Bedi, Dukhsingh Chauhan and Madan Solanki -- were produced before Sessions Judge S.P.H. Nagarkar in Mumbai Friday and remanded to police custody till Aug 5.

According to the CBI, the corruption case against Sweety Singh involves a complaint filed by Patil.

Patil alleged that Sweety Singh demanded a bribe of Rs.30 million for the withdrawal of a case filed against Patil by a group of conservancy workers employed by him (Patil).

Patil is a garbage collection contractor with the Nashik Municipal Corporation. Some 100 workers complained he was not paying their wages and had taken a bank loan of Rs.100 million (Rs.10 crore) in their name.

Sweety Singh allegedly approached Patil with an offer to escape the provisions of law if only he paid a bribe of Rs.30 million.

After some haggling, Patil promised to pay but alerted the CBI.

CBI detectives laid a trap for Sweety Singh and caught him in New Delhi Thursday evening while allegedly accepting the first instalment of the bribe from Patil.
