Hayden Panettiere's dolphin-saving mission last month has led to a warrant for her arrest in Japan, E! News reported.
"I learned that they have an arrest warrant out for me in Japan," the "Heroes" star told E! News. "We just found out."
Panettiere, 18, was part of a convoy of activists from the U.S. and Australia who on Oct. 30 paddled out on surfboards to protest the annual slaughter of dolphins and whales by Japanese fisherman.
Her group attempted to reach a pod of dolphins before it was driven into a nearby cove and massacred, but they were blocked by a fishing boat before they could reach the sea creatures.
After returning to shore, the group headed directly to Osaka and left the country to avoid being arrested for trespassing by the Japanese national police.
When asked what the arrest warrant could mean, Panettiere said, "Potentially jail, but I doubt it."
