Update | Thai police blame second Bangkok bombing on 'red shirts'

Prime Minister Prayuth Chan-ocha today called on Thais to be the “eyes and ears” of security forces in order to boost foreigners’ confidence in Thailand after the second explosion in the capital Bangkok in just over a month.

Police have detained three people in connection with the grenade explosion on Saturday night outside Bangkok’s Ratchadaphisek Criminal Court. No one was hurt in the attack.

Thai police today accused a network of ”red shirt” supporters of the toppled government of trying to destablise the kingdom after the bomb attack.

“We ask the public to be the eyes and ears of authorities because security must come first. We must rebuild confidence for foreigners,” Prayuth told reporters. “I will not bow to bad people.”

Two men were detained on Saturday night after a brief shoot-out with security forces that followed a grenade attack at the Criminal Court, which caused minor damage to the building’s car park but no injuries.

National Police spokesman Prawut Thavornsiri said they are hunting another man and two women from the same apparent cell.
