On Wednesday Thai police released a sketch of the man they believe carried out the bombing at a popular shrine in central Bangkok that killed 20 people.
Police spokesman Lt. Gen. Prawut Thavornsiri tweeted that a 1 million baht reward ($28,080) is on offer for information on the perpetrators. An arrest warrant was issued for the unidentified suspect Wednesday, the Associated Press reported.
Speaking of the bomber, national police chief Somyot Poompanmoung said: "He didn't do it alone, for sure. It's a network," according to the news agency. "Hopefully, he is still in Thailand," he added.
