Thai police say arrested man played key role in Bangkok blast

BANGKOK (Reuters) - A foreign man arrested by Thai police on Tuesday played a key role in the deadly bombing that ripped through a Bangkok shrine in August, Thai police spokesman Prawut Thawornsiri said. But Prawut said he could not confirm if the arrested man was the chief suspect seen on CCTV footage leaving a bag at the site of the Aug. 17 blast, which killed 20 people and stunned Thailand. The arrested man was also involved in a second smaller explosion in Bangkok on Aug. 18, Prawut said. Thai police have issued arrest warrants for three more foreign male suspects, he said.
