Police were involved in an unusual kind of chase on a motorway near Gothenburg on Saturday night. Their quarry was not escaped prisoners or speeding motorists, but rather two circus llamas. The camelids had escaped from Circus Maximum in Vallhamra, and made their way to the E20 motorway, the principal route between Stockholm and Gothenburg. Police tried to catch the creatures, but their efforts served more to alarm them, and they ran backwards and forwards across the motorway, Expressen reports. The chase continued for an hour before circus staff and police managed to catch the frightened llamas.
