12:45 p.m.

Thai police say the fingerprints of a foreign man arrested at Thailand's border with Cambodia match those they found on a bottle containing bomb-making material.

The bottle was among many items seized during a raid Saturday of an apartment on the outskirts of Bangkok where another suspect was arrested as part of the investigation into the deadly Aug. 17 bombing at the Erawan shrine.

Both suspects are being interrogated by the military and have not yet been charged.

National police spokesman Prawut Thavornsiri said Wednesday that the man arrested at the border on Tuesday "is important and is related to or conspired with people" behind the bombing that killed 20 people and wounded more than 120.
