Pakistani prisoner Sanaullah Haq, who was attacked by inmates in Jammu's Kot Bhalwal jail, died in a Chandigarh hospital on Thursday. Sanaullah suffered renal failure on Wednesday and doctors had said that his condition was "extremely critical". According to reports he was on a ventilator, remained unconsicious and was on dopamine and noradrenaline infusions to maintain his blood pressure. Sanaullah was injured during a scuffle with another inmate in Jammu jail earlier last week where he was serving life term after being convicted under TADA provisions. The incident involving Sanaullah came a day after the death of Indian prisoner Sarabjit Singh, who was brutally attacked on April 26 by six Pakistani inmates in Lahore's Kot Lakhpat Jail.
