BANGKOK (AP) — Thai police say a foreign suspect has been arrested in the investigation of a deadly shrine bombing in Bangkok.

National deputy police chief Chakthip Chaijinda said Saturday: "It is most likely he is related to the bombing at Rajaprasong," the neighborhood where the shrine is located. The blast at the Erawan Shrine on Aug. 17 killed 20 people, including foreigners.

The man was arrested Saturday in Nong Jok on the outskirts of the capital. Chakthip said, "We found bomb materials in his apartment."

National police spokesman Prawut Thawornsiri said that the arrested person is a foreigner, but refused to say if he was Turkish, as was reported by some local news organizations.

He said a news conference was planned later Saturday.
