"We filed the chargesheet in the special MCOCA court," a senior police official said.
According to police, a city-based businessman was called to Bangkok and was allegedly kidnapped for a ransom of Rs 15 crore by Shetty. The case was later handed over to the anti-extortion cell of the crime branch.
Shetty, who was wanted in several cases including contract killing and drug smuggling, had been arrested by Thai Police in Bangkok in August 2011 and deported to India.
Shetty formed his own gang after parting ways from Chhota Rajan in 2004 and was actively involved in extortions, kidnappings and contract killings, police said.
Shetty was earlier lodged in Nasik Jail after his conviction under the Narcotics Act for five years. However, he went to Bangkok after being released on parole.
