Bangkok bomb: Erawan shrine attacker was 'part of network', police say

The bomb attack that killed 20 people at Bangkok's Erawan shrine on Monday was carried out by a "network", Thailand's chief of police has said.

Investigators are trying to trace the main suspect, a man in a yellow t-shirt who was filmed by security cameras leaving a backpack at the shrine.

The Hindu shrine, popular with tourists and Buddhists, reopened on Wednesday.

Prime Minister Prayuth Chan-ocha has described the incident as the worst-ever attack on Thailand.

Thai police chief Somyot Poompanmoung told the Associated Press news agency on Wednesday that the shrine attack was the work of more than one person.

"He didn't do it alone for sure," he said, referring to the main suspect. "It's a network," he added, without giving further information.
