Thai police released an electronic sketch Wednesday of the alleged suspect in the bombing of a Bangkok shrine that killed 22 people, NBC News reported.
The drawing shows a young man with glasses and is apparently based on the person seen in surveillance video leaving a backpack near the scene.
Police have offered a 1 million baht ($28,080) reward for information leading to his arrest.
Authorities said they were keeping watch for the suspect at the country's borders, but police chief Somyot Pumpanmuang told a news conference that it was not clear how many people were involved in the attack or if they were still in the country.
