JAMUI, Aug. 24 -- An undertrial prisoner, arrested on charges of killing his wife on August 18, died in Jamui jail on Friday afternoon, police said. Family members alleged that he was killed inside the jail after he failed to pay extortion money to fellow inmates. Jail authorities, however, maintained that he died during treatment at a hospital. The deceased, identified as 22-year-old Dabloo Kumar Choudhary, was arrested by Simultala police on August 18 and sent to jail the next day. "From the jail, he called us from the number 8809855964 and demanded Rs.5,000 to 'buy life.' For failing to pay, he was tortured through the night. Later, we managed to pay Rs.2,000 through PhonePe," family members alleged. They further claimed that inmate Santoshi Yadav demanded the money, and when Choudhary could not arrange the remaining Rs.3,000, he was beaten to death. "For every undertrial prisoner, it is mandatory to pay Rs.5,000 for a seat in jail. Jail authorities have virtually lost control," the family alleged. A medical board conducted the postmortem before handing over the body to the family. Jail superintendent Sanjeev Kumar said, "The undertrial prisoner was rushed to the hospital after his condition suddenly deteriorated, and he died on the way."...
