Actor Sanjay Dutt, jailed in an arms case related to the 1993 Mumbai blasts, will not be pardoned, the Maharashtra governor has decided.A 2013 petition by former Supreme Court judge Markandey Katju seeking pardon for the actor has been rejected.Sources say governor Vidyasagar Rao rejected the petition on the recommendation of the state home department, which said it would set a bad precedent as the actor's conviction was confirmed by the Supreme Court.The 56-year-old actor was found guilty in 2013 of acquiring illegal weapons from those involved in the deadly 1993 attacks in Mumbai in which 257 people were killed, and hundreds injured. He was sentenced to six years in jail in 2007; he served 18 months but then was out on bail, fighting the conviction until a court in March 2013 ordered him back to jail in Pune.In 2007, Mr Dutt was cleared of conspiracy charges in the attacks but found guilty of illegal possession of an AK-56 rifle and a pistol, which he claimed he required to protect himself and his family during the rioting that erupted in Mumbai after a series of bombs exploded at the city's landmarks.The actor is currently out on parole for his daughter's nose surgery. His frequent breaks from jail have been criticised as evidence of VIP treatment. Between May 2013 and 2014, Mr Dutt spent over 118 days out of prison.Mr Dutt is due to be released in Feb 2016.
