Dental surgeon Rajesh Talwar, against whom the CBI did not find any evidence of killing his daughter Aarushi, had expressed his desire to practice in Dasna jail and the authorities had made arrangements in this regard.

"We repaired a chair used by the dentist as he had expressed his willingness to treat patients," Superintendent of Dasna jail Ramji Singh told reporters minutes after Talwar's release.

He said Talwar, who remained quiet for the initial days before he started talking with fellow jail mates, had two-to-three persons attached to him all the time so that no harm was done to him inside the jail.

The jail superintendent said the dentist preferred spending his time reading books.

"He refrained from watching television initially as all channels talked about his daughter only," Singh said.

He said whenever any one had asked the dentist about his daughter, his eyes were immediately filled with tears and in a choked voice he used to say, "I am the most unfortunate person on this earth who is facing charges for murdering his own sweet little daughter."

Singh said whenever someone had asked about Aarushi, Talwar always became depressed.

"So we later refrained from asking him about his daughter," he told reporters in Ghaziabad.
