BANGKOK—A Thai court on Thursday issued an arrest warrant for an unnamed suspect in a riverside blast that occurred a day after the bombing of a shrine in central Bangkok which killed 20 people.
Police spokesman Prawut Thawornsiri said the suspect appeared in a security video that shows a blurry image of an unidentified man in a blue shirt kicking a bag into the water near a busy pier on the night of Aug. 17, soon after the explosion at the Erawan Shrine.
