A police officer may have witnessed a young man collapse before he was released from police custody and hours later died, a coroner has heard.
Mohamud Hassan was arrested at his Cardiff home on the evening of January 8 last year on suspicion of a breach of the peace. He was released from Cardiff Bay police station at around 8.30am the next day without charge.
The 24-year-old was found dead in his bed shortly after 10.30pm that day at his flat in Newport Road, Roath. The death of Mr Hassan, who was of Somali heritage, sparked protests calling for answers from police.
