Peru has offered a reward of £24,000 for the capture of its former president, Alejandro Toledo.
A judge issued an international arrest warrant after accusations that he took $20 million (£16 million) in bribes.
The bribes were apparently given so a company could win a contract to build a highway from Peru to Brazil.
The reward is being given to anyone in the world who may be able to provide information on Mr Toledo.
Prosecutors believe there was a high probability Mr Toledo received the bribes - something Mr Toledo denies.
Peru's government it has information that Mr Toledo, who led the country from 2001 to 2006, is in San Francisco.
Authorities have also reached out to Israel because they believe Mr Toledo may take advantage of his wife's dual Belgian-Israeli citizenship in an attempt to seek refuge in the country, which doesn't have an extradition treaty with Peru.
