People ride their motorcycles past a digital billboard showing a sketch of the main suspect in Monday's attack on Erawan shrine, in Bangkok, Thailand, August 23, 2015. Thai authorities have tripled to $85,000 a reward for information leading to the arrest of the main suspect in the country's worst ever bombing. The words on top of the sketch read, "Criminal Record Registration Division", and the words on the right side of the billboard read, "Award for arrest 1,000,000 baht. Requesting the cooperation of citizens, if you have seen or have any clues, call 1599". REUTERS/Chaiwat Subprasom
