'The Otto I know and love'

The family of a 22-year-old US student in a coma who has been freed by North Korea after 15 months in jail have released video footage that they say was shot just before his arrest.

It shows Mr Warmbier and others throwing snowballs along with other members of his tour group to North Korea.

"This is the Otto I know and love," his brother Austin Warmbier said.
