In separate incidents, two prisoners in Chattogram died yesterday due to illness.
The deceased are Bilati Tripura, 45, from Khagrachhari Sadar upazila, and Omar Faruk, 57, from Cumilla, said jail sources.
Bilati, who was imprisoned at Khagrachhari jail, had been suffering from rabies and was admitted to Khagrachhari Sadar Hospital on Tuesday.
Later, doctors referred her to Chattogram Medical College Hospital (CMCH) for better treatment, but she died on the way, prison jailer Abu Fatah told The Daily Star.
She was accused of murdering one Kali Bandhu Das in Khagrachhari and was imprisoned on April 4 this year, he added.
Meanwhile, Omar Faruk, who was imprisoned at Chattogram Central Jail, fell sick and complained about chest pains at midnight yesterday. He was then shifted to the prison hospital for treatment, said prison jailer Nashir Ahmed.
As his condition deteriorated, Omar Faruk was later rushed to CMCH, where he died around 2am, the jailer said, adding that Omar was imprisoned after being arrested in a narcotics case filed with Kotwali Police Station in March.
The bodies were sent to Chattogram Medical College morgue for autopsies, officials said.
