MANILA, Philippines (AP) — Philippine police say they have arrested an Australian Islamic preacher with alleged links to Muslim extremists.

Chief Superintendent Prudencio Tom Banas said Robert Cerantonio, alias Musa, and a Filipino woman were arrested Friday in their apartment in central Lapu-Lapu City.

Police and immigration agents raided the apartment on the basis of a deportation warrant tagging Cerantonio as a “person of interest to the intelligence community.”

Cerantonio was placed under the custody of the Bureau of Immigration while the woman was taken by police for questioning.

A senior police official who refused to be identified because he was not authorized to speak to media, says Cerantonio was monitored giving lectures to Muslim Filipinos to support the Islamic State militant group that controls part of Iraq.
