Prayut said the suspect was arrested in Sa Kaew province, adding that he was not Thai and that police are checking the man’s nationality. He said the Turkish embassy has been informed of the arrest and that the suspect has been brought to Bangkok for questioning.
Nation TV reported that the suspect resembled the man in a yellow T-shirt, who was captured on CCTV leaving a backpack under a bench in the shrine compound. The backpack exploded minutes later, killing 20 people and injuring hundreds of others.
Police spotted the suspect when he was trying to sneak across the border into Cambodia from Aranyaprathet, Burapha Taskforce chief Maj-General Srisak Poonprasit said. The suspect had a black backpack, in which he was found to be carrying clothes similar to the ones the suspected bomber was seen wearing on the day of the attack.
