Thailand’s Prime Minister Prayuth Chan-ocha says a suspect matching the description of the bomber of a shrine in Bangkok has been arrested. The Thai leader said the suspect is “not Thai” and was seized near the border with Cambodia. The August 17 bombing killed 20 people and injured more than 100. The suspect was arrested Tuesday and is being questioned by police in the capital. Police are seeking three more suspects in the bombing. Officials on Tuesday released a photograph of a Turkish man and a drawing of two other men. The two are wanted for “illegal possession of explosives.”

The military says a female Thai suspect, whose picture was released Monday, is in another country and is cooperating with the investigation.
