BANGKOK: Police are trying to identify two men seen in a security-camera footage outside Siam Paragon shortly before two pipe bombs exploded there Sunday night.
A police source said video experts are now trying to magnify the faces of the two suspects so that arrest warrants could be sought against them.
Pictures captured from the footage showed the two men wearing white shirt and cap.
Nobody was injured in the incident.
The explosion under the sky path linking the mall and the Siam BTS station forced train services at the Siam Station to be suspended.
Police said the bombs were planted behind a power transformer.
Bomb disposal officers and crime detection officers from both the Pathumwan police station and the Metropolitan Police Division 6 rushed to the scene after the explosions took place and sealed off the area to gather evidence.
Police said the bombs were made of steel pipes.
Security has been heightened across the country following the double explosions.
Prime Minister Prayut Chan-o-cha and Deputy Premier and Defence Minister Prawit Wongsuwan implied that martial law would need to be retained following the incident - the first case of blasts in the capital since the coup last May.
"I have ordered security to be tightened because this case involves the well-being of the people," the prime minister told reporters.
Prawit, meanwhile, warned of stepped up security across the country. "We will strictly enforce security across the country. We need to have high security checks in some areas," he said.
"We can't say for now who is behind this. It could be people who have bad intentions, or are linked to politics or people who think differently," the defence minister said. - The Nation/ANN
