A report has emerged that Bangladeshi undergraduate student killed in his dormitory on Sunday days following his criticism of the government online was beaten for several hours before he died.
Fellow students who witnessed the event say Abrar Fahad was taken from his room around 20:00 (14:00 GMT) and beaten at least four hours.
The doctor who performed the autopsy on Fahad, who was 21, confirmed to the BBC his body was heavily bruised.
Several members of the Bangladesh Chhatra League (BCL) – the youth wing of the governing Awami League party – were detained in connection with the death.
The BCL has been widely accused of using torture and extortion against students.
