Authorities remove beam placed on Christmas Day to recreate Eisbach wave, which vanished in October

A row over the disappearance of a famous river surfing wave in Munich has escalated after authorities removed a beam inserted over Christmas to recreate the attraction.

The Eisbach wave on a side branch of the Isar River had been a landmark in the Bavarian city since the 1980s but it vanished in October after annual cleanup work along the riverbed.
