Otto Warmbier: US student sent home from North Korea dies bbc.com

The US student held in captivity for more than 15 months in North Korea has died a week after returning home.
Otto Warmbier, 22, was serving 15 years of hard labour for attempting to steal a propaganda sign from a hotel.
He was sent back to the US last Tuesday on humanitarian grounds – it emerged he had been in a coma for a year.
North Korea said he had contracted botulism but his family say North Korea subjected him to "awful torturous mistreatment" in detention.
A team of US doctors have also disputed North Korea's version of events.
