A 38-year-old Washington man has been arrested for allegedly throwing a rock at a monk seal on the shores of Maui in early May, an incident that was caught on video and quickly went viral.

The monk seal is well-known to locals who have named her "Lani."

Special agents with the National Oceanic and Atmospheric Administration arrested Igor Mykhaylovych Lytvynchuk near Seattle on Wednesday, May 13. Lytvynchuk, 38, is a resident of Covington, Wash., roughly 30 miles southeast from Seattle.

On May 5, bystanders took video of a man walking along the beach in the Lahaina area of Maui as he followed a monk seal, Lani, in the nearby shallow water. The seal was swimming and pushing a log. The man then took a large rock — one witness described it as the size of a coconut — and threw it at the seal, nearly hitting its head. The seal was startled and reared out of the water. Lani was motionless for a time, avoiding the shore, after the scare.
