Police chief General Somyot Poompunmuang said yesterday the Criminal Court had recently approved the third warrant.
The first two warrants were issued for two men captured on surveillance cameras planting the time bombs before fleeing the scene.
Police have taken action to solve the case, including securing arrest warrants based on available evidence, not baseless allegations or smearing efforts, he said.
A timeframe for finding and detaining the suspects has not been set so that investigators don’t come under too much pressure.
