CBI has started questioning gangster Chhota Rajan in Tihar prison in the murder trial of J Dey. The 56-year-old crime and investigations editor of mid-day was shot dead by motorcycle-borne shooters in June 2011, allegedly at the behest of Rajan.

The sources said the agency team yesterday reached Tihar Jail where Rajan is lodged after being deported from Indonesia and started questioning him after completing necessary formalities.

They said Rajan’s questioning in the case is likely to continue for some days.

A special MCOCA court in Mumbai had granted the CBI permission to interrogate Rajan in the case. Special Judge A L Pansare had allowed the CBI to question 54-year-old Rajan for 10 days starting January 27 before adjourning the case till February 5.

Rajan is facing around 70 cases in Maharashtra. The state government has handed over all the cases against him to the CBI.
