The death of a Chicago lottery winner has led to a murder investigation after a post-mortem examination found he died of cyanide poisoning.

Urooj Khan, 46, died suddenly as he was about to collect almost $425,000 (£264,000), but his death was initially attributed to natural causes.

Chicago police confirmed they were now investigating Khan's death as a homicide.
