Dutt, whose conviction in 1993 Mumbai serial blasts case was upheld by the Supreme Court in March this year, was brought to Yeravada jail at the crack of dawn yesterday.
He is lodged in a separate individual cell in view of his security needs, official sources said.
The Bollywood Khalnayak, who later reinvented himself with 'Gandhigiri' as Munnabhai, will be spending about three and half years in prison.
Sources said Dutt will be given prescribed manual work job in due course after formalities of admission are over. There will not be any special treatment to the actor except required due to the threat perception, they added.
