A prisoner in Pratapgarh district jail died of a heart attack, raising concerns over the health care of inmates. Jail officials reported that Satish Yadav, 32, was transferred from Naini Central Jail last year.

Yadav was admitted to a medical college after complaining of chest pain, according to deputy jailer Aftab Ansari. Although he was released Saturday evening, his condition worsened, leading to his death early Sunday morning.

Yadav, a native of Varanasi, faces several criminal charges, including murder. The authorities informed his family and sent the body for an autopsy.
