Prosecutors of a new organized crime unit in Panama raided the headquarters of law firm Mossack Fonseca, which is facing investigation after its documents, dubbed the Panama Papers, were leaked.
Half dozen police officers set up a perimeter around the offices while prosecutors searched inside for documents. The searches were also made at other subsidiaries of the firm in Panama and at the telephone company's computer support center.
Mossack Fonseca has denied any misconduct, saying it only set up offshore financial accounts and anonymous shell companies for clients and was not involved in how those accounts were used.
The search came a day after intellectual property prosecutors visited Mossack Fonseca to follow up on the company's allegations that a computer hack led to the leak of millions of documents about tax havens.
Mossack Fonseca filed a complaint charging the security breach before the first media reports working with the documents offered details on how celebrities, politicians and companies around the world were hiding assets in shell companies and offshore accounts.
