Dutt, sentenced to six years rigorous imprisonment under the Arms Act for illegal possession of an AK-56 assault rifle and a pistol, was sent to Arthur Road jail in central Mumbai till arrangements are made to shift him elsewhere.

The 48-year-old actor had spent close to a month in jail, a major part of it in Pune's Yerawada Prison, after being sentenced on July 31 but had been granted interim bail by the Supreme Court until he received a copy of the judgement.

Special Public Prosecutor Ujjwal Nikam said he would advise the prosecuting agency, the CBI, to appeal against Dutt's acquittal under the stringent Terrorism and Disruptive Activities (Prevention) Act (TADA).

"After reading in detail the judgement copy, the agency will decide whether to appeal in the Supreme Court against Dutt's acquittal under TADA," Nikam told reporters outside the high security court.

The court, after a trial spanning over 14 years, had convicted 100 persons for their involvement in carrying out the serial blasts on March 12, 1993 which killed 187 people and wounded over 700.
