A two-member committee has been constituted by Gazipur district administration to investigate the custodial death of writer Mushtaq.
"As far as we know Mushtaq collapsed in a washroom of the prison on Thursday evening. Later, he was taken to Shaheed Tajuddin Medical College and Hospital, where he was declared dead,” said Gazipur Deputy Commissioner SM Tariqul Islam.
"The two-member probe panel was formed on Friday night to investigate if there was any negligence during his treatment," he said, adding the committee has been asked to submit its report within two days.
The committee members are Executive Magistrate Mohamamd Wasiuzzaman Chowdhury and Umme Habiba Farzana.
Mushtaq reportedly suffered a heart attack inside his cell at Kashimpur prison on Thursday evening.
"He was rushed to Shaheed Tajuddin Medical College Hospital where he was declared brought dead," Senior Jail Superintendent Md Gias Uddin said.
An unnatural death case has been filed with the Gazipur Metropolitan Police's Sadar Police Station in connection with Mushtaq's custodial death.
The 53-year-old writer, who published the book "Kumir Chaasher Diary" under the pen name Michael Kumir Thakur, was picked up by Rapid Action Battalion (RAB) personnel from his Lalmatia home on May 2, allegedly for posts over the handling of the Covid-19 pandemic.
On August 20, he was shifted to Kashimpur prison, Gias Uddin said.
Calls for Mushtaq's release were widespread and sustained throughout his time in prison. Soon after his arrest, more than 300 dignitaries in Bangladesh issued a joint statement demanding his release, including cartoonist Ahmed Kishore.
