A senior Mexican official says prosecutors are trying to detain the former governor of Veracruz state on suspicion of corruption.

Interior Minister Miguel Angel Osorio Chung told Radio Formula on Wednesday that officials aren't sure where Duarte is, but believe he's still in the country.

Duarte stepped down as governor a week ago, saying he wanted to confront the corruption allegations, which he denies.

Critics say vast sums of state funds disappeared during the nearly six years he led the Gulf Coast state, which is plagued by drug gang violence. The governing Institutional Revolutionary Party has stripped Duarte of his party rights.

Prosecutors are also hunting for former Sonora state Gov. Guillermo Padres on suspicion of corruption.
