Medical student Abdoulaye Ba died on Cheikh Anta Diop University campus in Dakar last week during violent student protests.
An autopsy, widely reported in Senegalese media, found Ba suffered multiple traumas to his chest and skull, causing massive internal bleeding.
The report ruled out a natural cause, pointing instead to a major traumatic event leading to acute cardiorespiratory failure.
Authorities have not independently verified the autopsy, and the public prosecutor said evidence does not confirm rumours of physical violence.
The UCAD student association accused the prosecutor of stirring confusion and demanded full disclosure of the circumstances surrounding Ba’s death.
Students had led protests over unpaid stipend arrears, which escalated into clashes with police, according to government and media accounts.
Interior Minister Mouhamadou Bamba Cisse acknowledged the tragedy and admitted police misconduct while blaming students for campus destruction.
Videos circulated online showed security forces entering university grounds, firing tear gas, and students retaliating by throwing stones.
In footage authenticated by AFP, officers were seen striking a screaming man with blunt instruments, intensifying public outrage over the incident.
The death of Abdoulaye Ba has ignited a national debate over student rights, police accountability, and the handling of campus unrest.
The government faces mounting pressure to investigate fully while balancing public anger with claims of maintaining order at UCAD.
