BBC World reports a United Airlines flight was forced to make an unscheduled landing in Anchorage on Thursday evening due to a “passenger smearing faeces everywhere.”

Police said the man, a US resident of Vietnamese origin, made no threats.

It is not clear what led to the episode taking place.

“We received a report of a passenger who had messed up the bathrooms with his own faeces,” Anchorage Airport police spokesman Lt Joe Gamache said.

The passenger, a 22-year-old whose name has not been released, was co-operative and faced “no appropriate charges for anything criminal”, Lt Gamache added.
