Dutt, currently out on parole since Dec 21, 2013, was due to return to jail Jan 21, but he sought and was given extension of another month (till Feb 21) in his parole.
Now, he has applied for another month-long extension.
Dutt has written to the Pune divisional commissioner, who has directed the Khar Police in Mumbai to verify the reasons for parole extension cited in the application, a police official said. The verification report is expected in the next few days.
An accused in the March 1993 Mumbai serial blasts case, Dutt is serving the remaining 42 months of his five year prison sentence.
