A pair of hikers in New York called emergency services to report that a third member of their group had died, but when a park ranger responded to rescue them it turned out they were just high on hallucinogenic mushrooms, officials say.

The third hiker was uninjured - and not dead - and the hikers were "in an altered mental state", according to a report issued by parks officials.

The incident took place on 24 May on Cascade Mountain in the Adirondacks High Peaks of upstate New York.

The third person also called 911 during the hike, "and was not injured", the report states. They were allowed to continue their camping trip, while the pair were taken to police.
