The arrest warrants were made on charges of organised crime, arson, causing explosion and illegal possession of explosives.
The police said they are hunting at least 15 suspects related to the series of bombings.
Six bombs exploded in Bangkok’s Chong Nonsi BTS station, Rama IX road, the Government Complex on Chaeng Watthana Road, and King Power building on August 2. They took place as the capital city was hosting the 52nd ASEAN Foreign Ministers’ Meeting (AMM-52) and related meetings that were attended by top diplomats from the ASEAN member states as well as the US, China, Russia, Japan, and many other countries.
One day later, three more bombs also went off at three ATM machines in Pattani province.
Two men have been detained on August 2, accused of planting two bombs, which authorities earlier had said were fake, in front of the police headquarters in central Bangkok a day earlier.
