Panamanian investigators on Friday raided a property used by Mossack Fonseca, the law firm at the center of a massive leak of offshore financial data, removing bags full of shredded documents as evidence, a local prosecutor said.

"We have secured a large amount of evidence found in the location," said organized crime investigator Javier Caraballo.

He said they also found many shredded papers, which they removed as evidence.

In a statement, Mossack Fonseca said it had digitized all its documents and that the shredded papers taken from its premises were bound for recycling. The law firm added that as a result of a previous search, prosecutors already had copies of all the documents they removed on Friday.

Leaks from the Panama-based law firm, dubbed the "Panama Papers," have embarrassed several world leaders and shone a spotlight on the shadowy world of offshore companies.

Mossack Fonseca, which specializes in setting up offshore companies, has said it broke no laws, destroyed no documents, and all its operations were legal.

Governments across the world have begun investigating possible financial wrongdoing by the rich and powerful after the leak of more than 11.5 million documents from the firm.
