Thailand police have released a sketch of the main suspect in the Erawan Shrine bombing in Bangkok that killed 20 people and wounded over 100.

They’ve also offered a THB1 million reward to anyone who can offer information about his whereabouts.

Judging by the sketch from the Lumpini Police Station, the man looks to be in his 20s and Caucasian or Asian. The document says that the man is wanted for premeditated murder.

In CCTV footage, the suspect can be seen walking into the Erawan Shrine area Monday night wearing a yellow shirt and a backpack.

He then sits down on a bench, leaves his backpack on the bench and walks away looking at his mobile phone.

Minutes later, the explosion occurred.
