On Monday, a bombing at the Erawan Hindu shrine in Bangkok, Thailand injured many and disrupted life in one of the Thai capital's popular tourist and affluent neighborhoods. Half of the victims were foreigners. Nationals from China, Hong Kong, Malaysia and Indonesia were among the foreigners killed in the attack.

A reward of one million baht or $28,000 in U.S. dollars has been offered for information leading to his arrest.

According to the Bangkok Post, Chief Poompanmoung also said that the bomb that was tossed from a bridge in at Bangkok's Sathorn pier is the same bomb that was used in the shrine bombing. He also believes that both Thais and foreigners were involved in the bombing.

"I can tell you now that there are not only foreigners involved in the incidents but some Thais must have taken part," he said.
