"SeaWorld Accused of Infiltrating Animal Rights Group in California"

"SAN DIEGO -- An animal rights group said SeaWorld Entertainment Inc, known for its dolphin and killer whale performances, sent an employee on secret missions to infiltrate events organized by the group in an attempt to undermine its work.

For years, People for the Ethical Treatment of Animals (PETA) has campaigned against SeaWorld over its treatment of killer whales. In 2011, the group sued the company for violating the civil rights of a captive orca. The suit was dismissed. Since then, PETA has repeatedly called on SeaWorld to send its captive orcas to seaside sanctuaries.

In a statement on Tuesday, the Norfolk, Virginia-based animal rights group said SeaWorld had become "so upset" that it deployed one of its human relations employees to masquerade as an activist, sending him on undercover missions at protests and organizational meetings in California."
