"Special Judge O.P. Saini sent Chhota Rajan to judicial custody till 3 December after the CBI told him the don was not required for further police custody," sources said.

The sources said the court hearing took place at the CBI headquarters under tight security where the don was presented after the expiry of his CBI custody.

On 16 November, the court had extended the CBI custody of Chhota Rajan till 19 November.

A CBI official said the probe agency did not require further custody of Chhota Rajan in the fake passport case and till now had not received the case files of other cases pending against him.

He said the CBI was in the process of getting files of 71 other cases lodged against him from the Maharashtra Police.

The central agency had booked Rajan and unknown public servants in a fake passport case on charges of criminal conspiracy, cheating, cheating by impersonation, forgery of document under the Indian Penal Code.

The agency claimed Rajan got prepared an Indian passport in the name of Mohan Kumar and an address in Karnataka. CBI sources confirmed that Rajan reached Australia on 22 September, 2003, on the same passport and a tourist visa.

Rajan is wanted for over 85 crimes, ranging from murder to extortion, smuggling and drug trafficking. Apart from Maharashtra, he has cases pending against him in Delhi, Uttar Pradesh, Gujarat and with the CBI.

Mumbai Police has nearly 75 cases against Rajan, including 20 of murder, four under Terrorist and Disruptive Activities (Prevention) Act, one under Prevention of Terrorism Act and over 20 cases under the stringent Maharashtra Control of Organised Crime Act.
