Panamanian investigators have raided a property used by Mossack Fonseca, the law firm at the centre of a massive leak of offshore financial data, an official from the local prosecutor's office says.
The official, speaking on condition of anonymity, said a statement with more details would be sent later.
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.
Panamanian media reported that investigators left a Mossack Fonseca storehouse with bags full of shredded papers.
Mossack Fonseca, which specialises in setting up offshore companies, has said it broke no laws, destroyed no documents, and all its operations were legal.
