A floating "island" in a reservoir in British Columbia has turned up about 20 miles (32km) from where it was last spotted, after seeming to vanish in July.

The organisation that manages the reservoir says it initially believed the discovery was a "hoax".

BBC Verify has used satellite imagery to track its journey and looked into why it travelled such a distance - as Jake Horton reports.
