Thai officials are seeking two additional people in connection with their investigation of a deadly bombing in Bangkok. Officials released a picture of a woman and a drawing of a man suspected of involvement in the bombing earlier this month. The new information came after police raided an apartment building on Sunday. Monday, national police said they seized fertilizer, explosive devices and digital watches from several rooms they searched.

Police also announced Monday that a reward for information about the bombing would be paid to the police. Officials announced that police would receive about $83,000 after a 28-year-old foreign man was arrested on Saturday.
