New Delhi: The Supreme Court on Thursday sentenced Bollywood actor Sanjay Dutt for 5 years in prison in connection with the 1993 Mumbai blast that claimed 257 lives.
He has already served 18 months in prison and he will now have to serve the remaining three and a half years in jail. He was earlier sentenced to six years in prison which the Supreme Court reduced to five years. Court gives him four weeks to surrender.
Dutt and his lawyers had expected a very lenient sentence, but that did not happen. His lawyer said the next course of action would be decided after the judgment copy is studied in detail. 
The case pertains to the 1993 Mumbai serial blasts in which 100 people were convicted out of which 12 were awarded death penalty and 20 were given life sentence by a Disruptive Activities (Prevention) Act (TADA) court.
Sanjay Dutt was one amongst them.
The court upheld the death sentence of blast accused Yakub Memon. He is at present lodged in the Nagpur jail. The court commuted the death sentence on 10 others to life imprisonment. The court took the view that the economic condition of the convicts was weak.  
Earlier, Dutt was sentenced to a jail term of six years for illegal possession of firearms acquired from terrorist acquaintances, who were responsible for the 1993 Mumbai bomb blasts on July 31, 2007.
He was granted bail by the apex court on November 27, 2007.
