Thai police release sketch of Bangkok bomb suspect

Thai police have released a sketch of the key suspect in the investigation into the Bangkok bomb blast that killed at least 20 people.

The man was shown in CCTV footage leaving a backpack at the scene, checking a phone and then casually walking away before the blast.

The sketch released by police shows a man with medium-length black hair, a beard and glasses. It’s unclear from the sketch if he is Thai or a foreigner.

Police say others could be behind the blast, although the man in the sketch is a suspect.
