File-sharing site The Pirate Bay says it will sue a Finnish anti-piracy site for pirating the design of its website.

The Finland-based Copyright Information and Anti-Piracy Center created a website urging people to find more legal means to download music, TV shows and other digital content.

To emphasize its intent, the CIAPC site intentionally borrowed the exact design and style of The Pirate Bay site, CNET reported Thursday.

The Pirate Bay, although frequently in legal hot water itself over allegations of copyright violation and piracy, threatened to sue.

"We are outraged by this behavior," a Pirate Bay spokesman told TorrentFreak. "People must understand what is right and wrong. Stealing material like this on the Internet is a threat to economies worldwide. We feel that we must make a statement and therefore we will sue them for copyright infringement."

The Pirate Bay's usage policy states its site content may not be used by organizations without permission.
