The 11-year-old tahfiz school student whose legs were amputated, following beatings from an assistant school warden, may also lose his arm.

Doctors managed to dissolve a blood clot on his left shoulder, which is still in danger of amputation, Mohamad Thaqif Amin Mohd Gaddafi's aunt Dzuaidah Ahmad told reporters at Hospital Sultanah Aminah, Johor Baru.

There is a likelihood he could lose his right arm, which was operated on Saturday to treat a blood thinning condition, she reportedly said.

"The doctors told us they will decide at 8pm tonight if they still need to amputate (the right arm). I was told that it will be done if Thaqif's condition does not improve," she was quoted as saying by the New Straits Times.

If need be, his arm will be amputated at the elbow, Bernama quoted her as saying.

The boy, who is in a comatose state, had his legs cut off to save his life after the blood cells and tissues were destroyed by bacterial infection.

His right hand had also turned black due to the same infection while blood clots appeared on his left shoulder.

The boy had in his diary reportedly detailed his suffering at the school and prayed his parents would allow him to transfer from the Johor religious school.

The school assistant warden, who has been remanded over the case, is a convicted felon who served 15 months in jail for theft.

Tahfiz schools, private institutions where students mostly learn to memorise the Quran, do not come under the purview of the education ministry. Many of such schools are nevertheless registered with state religious affairs department.

Prime Minister Najib Abdul Razak today handed over RM80 million aid to all registered tahfiz and Sekolah Menengah Agama Rakyat (state religious schools), allocated under a fund to improve school infrastructures.

Of the figure, said to be the highest ever given to Islamic schools, RM30 million will be used to develop tahfiz education through the National Tahfiz Education Policy, he said.

"If it is the desire of parents (to send their children to tahfiz schools), then it becomes the government's duty to determine that it not only remains as an option for parents, but an option that can produce successful human beings," Najib was quoted as saying by Bernama.

Meanwhile, Johor's Sultanah Raja Zarith Sofia Sultan Idris Shah had instructed Johor executive councillor in charge of health, Ayub Rahmat, to carry out medical checks on students of the same tahfiz school, who all alleged to have been beaten.

She instructed this after visiting Mohmad Thaqif in hospital today, The Star reported.
