Foreigner Arrested in Connection With Bangkok Shrine Bombing

A police spokesman said he had no comment on the arrest, which was the second in the investigation of the Aug. 17 bombing, which killed 20 people. The man’s name and nationality were not released.

Thai news media reported that the man had been detained at the Thai-Cambodian border. Reports showed an image of a lanky man with the beginnings of a beard in the custody of soldiers.

The authorities have been searching for a man who was seen in video footage placing a backpack under a bench near the shrine minutes before the explosion. The attack was the worst bombing in recent Thai history, and it struck in the heart of Bangkok’s main shopping district.

The first arrest in the investigation was announced Saturday. That man was also said to be a foreigner; his name and nationality also have not been released. On Monday, the authorities issued two arrest warrants in connection with the case, one of which was for a 27-year-old woman from a Muslim area in southern Thailand whose family said she had moved to Turkey weeks before the bombing.
