Ch. Rajesh, an under-trial prisoner, died at the Government General Hospital (GGH) here on Thursday while undergoing treatment. He was a habitual offender involved in petty cases, particularly pick-pocketing. He was serving prison sentence in a case pending with the Krishnalanka police. Rajesh was shifted to the GGH from the sub-jail on Wednesday after he fell ill and died almost 24 hours later.
