“The military’s Burapa Task Force was able to arrest a man who resembles the yellow-shirt suspect believed to be involved in the Rajaprasong incident and wanted according to the arrest warrant, at the Thai-Cambodia border in Aranyapratet District of Sa kaeo Province,” said Winthai in a television address to the nation.
Fourteen foreigners were among those killed in the blast, which the military government said was aimed at dealing a blow to an already ailing economy.
The arrest came after security forces detained a first foreign suspect in weekend raids on the outskirts of Bangkok, in which they also found explosives.
“The police has also asked the court to issue arrest warrants for three more suspects. At the moment, there are a total of seven arrest warrants issued,” Winthai added.
The man arrested on Tuesday was detained in Sa Kaeo province to the east of the capital near the Cambodian border.
Thai media aired video of a thin man in a baseball cap, sunglasses and with a short mustache. Police displayed some of the contents found in the arrested man’s bag, which included a pair of military-style beige combat fatigues, a mobile phone and an assortment of documents and books. Police said the suspect has been transferred to the capital for questioning.
Thai authorities have been looking into a possible Turkish connection after fake Turkish passports were seized and police requested a Turkish translator to assist in questioning the 28-year-old man they arrested on Saturday.
The authorities have not confirmed the first suspect’s identity or nationality. He is charged with possessing illegal explosives.
