Mamadou Djouma Bah, 17, being accused of using his phone during Guinea’s national school‑leaving exam on 15 July, was arrested alongside other students suspected of exam fraud.

Two days later he was convicted and sentenced to six months in prison, five of which were suspended.

While serving a month in a prison in the city of Kindia, his health deteriorated, prompting a transfer to a regional hospital where he was treated for complications related to sickle cell disease.

He died several days later, with the prosecutor noting that the death occurred “under the care of his treating physician.”

His father, Mamadou Saliou Bah, has spoken to the BBC, blaming authorities for denying adequate medical care and demanding a thorough investigation.

He recalls his son’s last words, “Dad, I’m dying,” and calls for the release of other detained students to “protect the nation’s future.”

Human rights organisations have urged an independent inquiry into the circumstances of his death and the detention of classmates, while the education ministry expressed deep sorrow and condolences to the family.
