Dutt was earlier sentenced to five years in jail for possession of arms, which were a part of the consignment used in the 1993 blasts.
The actor, who was on bail during the trial, had surrendered in May 2013 after the Supreme Court upheld his conviction.
Dutt was let out in February 2016, eight months early, on account of his good conduct while in Pune's Yerwada prison.
The report was submitted in response to a public interest litigation filed by Pune resident Pradeep Bhalekar, questioning the regular paroles and furloughs granted to Dutt when he was serving his sentence.

Bhalekar, in his petition, alleged that Dutt was given undue favour by the prisons department by granting him remission.
"The Maharashtra Prisons (Remission System) Rules provide for remission of up to three days per month for good behaviour, discipline and so on. In the present matter at hand, as per the rules, the accused (Dutt) is entitled for 256 days remission which comes to eight months and 16 days," the report said.
However, the same was later allowed considering the accused's "conduct and behaviour" and Dutt was released from jail on February 25, 2016, the report said.
The high court perused the report and posted the petition for further hearing after two weeks.
During the investigation and the marathon trial, Dutt spent 18 months in jail.
On July 31, 2007, the TADA court in Mumbai sentenced him to six years' rigorous imprisonment under the Arms Act and imposed a fine of Rs 25,000.
During his imprisonment, he was granted parole for 90 days in December 2013 and for 30 days later.
