Murky dolphin deaths at Florida theme park prompt law enforcement raid

State investigation under way at Gulf World after four dolphins have mysteriously died in past six months

Wildlife officials and law enforcement officers have raided a Florida marine theme park where several dolphins died in mysterious circumstances, and activists filmed survivors in tiny pools swimming in murky green water.

Agents served a search warrant on Thursday evening at the Gulf World Marine Park in Panama City Beach, where the owners, the Mexico-based Dolphin Company, last week refused access to Florida fish and wildlife conservation commission (FWC) rangers seeking to conduct a wellness check.
