US animal rights activist Ric O'Barry who featured in "The Cove", a documentary about dolphin slaughter in a Japanese town, has been detained in Tokyo by immigration authorities after being denied entry to the country, his supporters said Wednesday. O'Barry, 76, was held by immigration officials at Toyko's Narita International Airport on Monday and interrogated repeatedly, they said, citing his lawyer. O'Barry appeared in "The Cove", the Oscar-winning documentary which drew worldwide attention to the annual dolphin hunt in the small Japanese town of Taiji, and has frequently visited Japan and the fishing community to protest against the killing of the mammals.
