Dutt's lawyer Satish Maneshinde met the star on Wednesday in barrack number one of the jail, which is used to hold people facing trial.
After the meeting, Maneshinde said Dutt was doing fine and denied reports of him having some health problems.
A man accused of cheating, who was taken from Arthur Road Jail for a hearing in court, claimed he too was confined in barrack number one and had seen Dutt in a state of shock on Tuesday. The man claimed Dutt ate only fruits and refused other food.
Jail authorities were tight-lipped and did not divulge information about the celebrity prisoner who spent 16 months in the same prison in two spells after his arrest in 1993.
Barrack number one of the jail in central Mumbai houses older prisoners and well-to-do undertrials, sources said.
High-ranking officials, inluding Inspector General of Prisons Satish Mathur, DIG (Prisons) S P Yadav and Arthur Road Jail Superintendent Swati Sathe today held a meeting to discuss whether Dutt, a convict, can serve his sentence in a jail meant for persons facing trial.
