The actor has already served 18 months in jail 20 years ago; the Supreme Court has directed him to serve another 42 months, reducing a trial court sentence of six years to five years.
At his home in Mumbai's Bandra, a green cloth has been draped on the gate so nothing is visible from outside. Members of the film fraternity, which has stood steadfast by the actor, are visiting him. A large posse of policemen has been deployed outside his house.
Mr Dutt is expected to surrender at around 4 pm today, when a deadline set by the court elapses. Paperwork will be done at Arthur Road, the local area jail for Mr Dutt, but only under-trials are kept there. Mr Dutt, as a convict, will be moved to another jail, most probably Pune's Yerawada Jail where he was lodged the last time.
On Tuesday, Mr Dutt had pleaded in court that he be allowed to surrender directly at the Yerawada Jail as he feared a threat to his life from "fundamentalist groups." On Wednesday, he withdrew his plea, without giving reasons.
The police and jail authorities have promised adequate security for Mr Dutt, but said no special arrangements have been made for the celebrity at the Pune jail.
As the date for his surrender drew closer, however, the actor appealed that he be given six months more to complete his seven films on the floor since it affected the livelihood of many people. The court gave him a month instead to wrap up all work. That month ends today.
On Tuesday, the Supreme Court rejected the petition of one of Mr Dutt's producers that he be given more time to finish his film. Last week, the court had also dismissed Mr Dutt's plea seeking a review of its March judgement.
Sanjay Dutt has been convicted and sentenced for illegally possessing a 9 mm pistol and an AK-56 rifle that were part of a consignment of weapons and explosives brought to India for coordinated serial blasts that killed 257 people and injured over 700 in 1993.
Two men, Keri Adajania and Yusuf Nullwala, who destroyed the AK-56 rifle, will also surrender with Mr Dutt today.
