The Sun reports:
A dolphin died after marine park bosses allowed a deafening rave yards from its pool. Wildlife experts warned the banging techno at the two-day dance event would lead to stress among the ten dolphins. Animal activists even turned up to protest at Connyland marine park in Lipperswil, Switzerland.
Shadow, an eight-year-old dolphin, appeared very distressed and disoriented after the event, and was later found dead.
An activist said: "The sound levels dolphins heard were comparable to a pneumatic drill." Connyland bosses denied any wrongdoing.
