A tourist accused of throwing a large rock at an endangered Hawaiian monk seal known as “Lani” is now facing up to $70,000 in fines and possible federal prison time after authorities say the incident violated major wildlife protection laws.

The confrontation allegedly took place on May 5 in Lahaina, Maui, where a visitor was filmed targeting the protected marine animal. The video quickly went viral, triggering widespread outrage across Hawaii and beyond, with conservationists and residents calling for accountability.

Federal authorities identified the suspect as Igor Mykhaylovych Lytvynchuk, 38, of Covington, Washington. On May 13, he was arrested near Seattle by special agents from the National Oceanic and Atmospheric Administration (NOAA) following an investigation into the incident.

Officials say the case involves potential violations of both the Endangered Species Act and the Marine Mammal Protection Act, which protect vulnerable species such as the Hawaiian monk seal—one of the rarest marine mammals in the world. If convicted, he could face up to one year in federal prison, in addition to significant financial penalties.

A federal prosecutor described Hawaii’s wildlife as “unique and precious,” stressing that federal authorities are committed to protecting endangered species and prosecuting anyone who harms or harasses them.

The viral footage sparked intense public reaction online, with many condemning the alleged act. Some local reports and eyewitness claims also circulated about confrontations following the incident, though officials have not confirmed all details surrounding those accounts.

During a legislative committee discussion, lawmakers cited the case in reference to repeated incidents of tourist-related wildlife interference. One lawmaker praised public frustration but also reiterated that any response must remain within legal boundaries, noting that violence is not officially condoned.

The suspect is currently in custody in Washington state and is scheduled to make his first federal court appearance on May 14 at 9:00 a.m.

Meanwhile, “Lani” has become a symbol of growing calls in Hawaii to strengthen protections for endangered wildlife and increase enforcement against animal harassment cases involving tourists.
