Police have carried out searches of the home and offices of former French President Nicolas Sarkozy as part of a campaign financing probe.
A law firm in which Mr Sarkozy owns shares was also searched, reports say.
The investigation is related to allegations that Mr Sarkozy’s 2007 presidential election campaign received illegal donations from France’s richest woman, Liliane Bettencourt.
Mr Sarkozy has previously denied all wrongdoing.
He is currently in Canada with his family, his lawyer, Thierry Herzog, told the AFP news agency.
In presidential elections in May, Mr Sarkozy lost to Socialist challenger Francois Hollande, and his presidential immunity from prosecution ended on 16 June.
Tens of thousands of euros were allegedly funnelled to Mr Sarkozy’s campaign by Ms Bettencourt’s office.
Individual campaign contributions in France are limited to 4,600 euros ($5,800).
