On his first night in the jail, Roy ate a single roti with dal and slept very late, said jail officials.
Roy has been lodged in barrack no. 4 along with two directors of his company - Ashok Roy Choudhary and Ravi Shankar Dubey.
According to jail officials, the three were heard talking till late in the night on the legal battle that lies ahead of them.
"He will have to sleep on the floor and have to eat jail food. Visitors will be allowed to meet him only twice a week and that too from the list of ten people he will have to submit at the time of admission," he said.
Soon after he reached the jail premises around 8 pm on Tuesday, a doctor examined him for any medical condition as part of a normal procedure.
Roy, who calls himself the managing worker of Sahara India Pariwar - the largest private sector employer in the country - will be allowed to meet visitors only twice a week.
The Supreme Court sent Roy and two others to judicial custody till they present a concrete proposal to return the balance of Rs 19,000 crore they collected from investors through optionally fully convertible debentures.
Tihar Jail spokesperson Sunil Gupta said Roy was kept at Tihar Complex where he was treated like any ordinary prisoner.
