Police in Thailand say neither of the two men detained in relation to the deadly bombing in Bangkok last month is believed to be the main suspect.
That person was seen on security footage wearing a yellow T-shirt and placing a backpack under a bench at the Erawan Shrine, moments before a blast that killed 20 people.
The two arrested men, identified as Adem Karadag and Yusufu Mieraili but whose nationalities remain unconfirmed, are thought to be part of a group that orchestrated the bombing.
