Jail authorities on Thursday complained to a special court that prime accused in 26/11 terror attack case Mohammed Ajmal Kasab has refused to eat food and thrown away utensils in his cell saying that he wants to have mutton biryani.

The judge M L Tahaliyani reprimanded Kasab for his rude behaviour and warned him to behave himself or else face stringent action.

This is not for the first time that Kasab has thrown tantrums. Even earlier, he had thrown away the utensils in which he was served food, the jail authorities complained. Kasab's behaviour was brought to the notice of the court after he refused to eat food on Wednesday and banged the utensil against the wall.

The jail authorities informed the court that Kasab was served same food which was given to other prisoners.

When Judge M L Tahaliyani asked Kasab whether he had behaved rudely with jail staff, he stood up and said "Yes sir".

Kasab is lodged in the high security central prison at Arthur Road. The court is also housed in the same compound.

Special Public Prosecutor Ujjwal Nikam condemned Kasab's behaviour saying he was throwing tantrums every now and then.

Nikam said he had read reports in a section of the media that on Raksha Bandhan day, Kasab had asked his lawyer after the court proceedings whether anyone would tie Rakhi to him.

This, he said, was deliberately leaked to the media and the ploy of Kasab was to gain sympathy of the people. Kasab is very clever and should not be allowed to throw tantrums, Nikam said.

Meanwhile, jail sources said they would keep a strict watch on Kasab. There are CCTV cameras installed in his cell and his movements are being monitored, they said.
