Thai police have released video of the suspected bomber in Monday’s deadly blasts in Bangkok. At least 22 people died and 120 others were injured. Most of them were foreigners.

The video was taken from a security camera outside the Erawan Shrine where the explosions occurred. It shows a dark-haired man in a yellow shirt. The man sits and takes off his backpack on a bench, leaving it behind as he walks away. Police said the blast occurred shortly after he left.

Another explosion occurred on Tuesday in Bangkok. It happened after someone dropped an explosive device off the King Taksin Bridge. The explosion occurred in the water, and did not cause injuries.

Thai Prime Minister Prayuth Chan-ocha said Tuesday the government will “work to find the perpetrators and bring them to justice as soon as possible.”
