E! Online is reporting that there is an arrest warrant out for Hayden Panettiere's arrest in Japan. Her heroic dolphin-saving mission last month wasn't without its consequences. "I learned that they have an arrest warrant out for me in Japan," the Heroes star told E! News exclusively Wednesday. "We just found out."

Panettiere said, 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.

Now it looks like the scare's not quite over for the actress.
