Controversial marine conservation group Sea Shepherd, known for intervening in the world’s oceans, says its founder has been arrested.
Paul Watson was detained at Frankfurt airport in Germany, according to the environmentalists who say he now faces extradition to Costa Rica.
The US-based group says the arrest relates to a confrontation in Guatemalan waters a decade ago involving a Costa Rican vessel illegally fishing sharks for their fins.
Sea Shepherd has made headlines with its direct action campaigns against whaling activities. It regularly disrupts Japan’s annual whale hunt.
