The 52-year-old actor was served dal-roti and vegetables for dinner, but according to Press Trust of India, he refused it. He wasn't allowed to get food from outside.
This morning, Salman Khan was served tea and khichdifor breakfast but he reportedly again refused food.
This is the actor's fourth stint in this prison. He has spent a total of 18 days in the jail in 1998, 2006 and 2007.
"He will have a simple wooden bed, a rug and a cooler in his cell. He was given normal jail diet like Dal chapatti and the morning meal will include simple khichdi," Mr Singh said on Thursday evening. The actor was given four blankets for the night.
His bodyguard were allowed to bring in a change of clothes for him.
Mr Singh said that the actor had slightly high blood pressure when he arrived in jail, but it soon settled to normal.
On the reported threat to Salman Khan from gangster Lawrence Bishnoi - who is lodged in a different jail - Mr Singh said the actor may be kept with a few other prisoners from Friday "so that he is not alone considering the threat to him."
Salman Khan has asked for bail on grounds that the witnesses against him are not reliable. He was sentenced to jail after the court declared him guilty of shooting and killing two blackbucks - rare endangered antelopes - near Jodhpur in October 1998, when he was working on a multi-starrer "Hum Saath Saath Hain". His co-stars Saif Ali Khan, Tabu, Sonali Bendre and Neelam Kothari were also said to have joined him in the late night hunt but they were acquitted for lack of evidence.
Salman Khan's two sisters, Alvira and Arpita, are still in Jodhpur after they attended the court hearing. Reports suggest more family members, including the actor's brothers Arbaaz and Sohail Khan, may arrive today.
