Dramatic CCTV video has emerged showing a suspected hand grenade exploding near Sathorn Pier in Bangkok on Monday afternoon, one day after an explosive claimed 21 lives and left 123 injured in the Thai capital.

The second blast comes as Thai police hunt for the suspected bomber behind last night’s blast, who was captured on CCTV near the Erawan Shrine blast site.
