Dutt, undergoing sentence for his conviction under the Arms Act in the 1993 blasts, had applied for parole to the Pune Divisional Commissioner Prabhakar Deshmukh in whom the authority to grant parole is vested.
"He has been granted one-month parole on the recommendation made by the prison officials. The date of his release on parole will be decided by them after completing the formalities," Deshmukh told PTI.
Deputy Inspector General of Prisons R Dhamne, however, said the jail authorities were yet to receive the order of parole sanction from the office of the Divisional Commissioner.
Earlier, the actor had availed of 15 days leave of furlough, extending it further by another fortnight in October on medical grounds.
