The explosion took place at the famed Erawan shrine where thousands of people flock to pray everyday. The shrine is home to a golden statue of Phra Phrom, the Thai representation of Brahma, the Hindu god of creation.

National police chief Somyot Pumpanmuang believes the bombing was a group job and the attack was planned a month in advance. He also believes that the main suspect is foreign but not part of a "international terrorist network."

According to CNN, a taxi motorcycle driver named Kasem Pooksuwan picked up the suspect shortly after the blast. During the ride, Pooksuwan noticed that the passenger was "calm."

"When I dropped him, he still appeared very calm, just like a normal customer. He seemed not in a hurry at all," he said. He also said the suspect gave him a piece of paper with the name of a city park in English and took him there.

So far, no arrests have been made, and the two suspects who turned themselves in have not been charged with any crime. Little is known about the main suspect, who was wearing a yellow shirt and had a backpack, according to security video footage.
