Bangkok bomb: Second foreign suspect arrested

A second foreign suspect has been arrested in connection with the deadly bombing at a Bangkok shrine in August, the Thai prime minister has revealed.

The male suspect was arrested in Sa Kaeo province, east of Bangkok on the border with Cambodia, Prayuth Chan-ocha told reporters.

"He is a main suspect and a foreigner," he was quoted as saying.

A foreign man was arrested in Bangkok on Saturday over the blast at Erawan Shrine, which killed 20 people.

Bomb-making materials and 10 passports were found at the apartment in Nong Jok on the outskirts of Bangkok, police said.

Thai military authorities have been interrogating him, but they have not yet released his name or nationality.

It is unclear whether either of the two arrested men are the prime suspect, who was seen on a security camera leaving a backpack at the crowded shrine shortly before the bombing on 17 August.

On Monday Thai police issued arrest warrants for two suspects - a 26-year-old Thai Muslim woman, Wanna Suansan, and an unnamed foreign man.

However, a woman who claims to be Suansan told a reporter she was living in Turkey and had last been in Thailand three months ago.

Speaking to AFP news agency by telephone, the woman said she was living in the central Turkish city of Kayseri with her husband and that she was "shocked" to have been named as a suspect.
