Thai police say a key suspect in the Aug. 17 bombing at a Bangkok shrine that killed 20 people has fled to Turkey.

Police had previously said the man, carrying a Chinese passport in the name Abudureheman Abudusataer, may have directed the bombing of the Erawan Shrine. They had discovered that he left Thailand on Aug. 16 for Bangladesh, and speculated that he might have gone to China.

However, national police spokesman Prawut Thavornsiri said Monday that information gathered by Thai police and Bangladeshi officials showed that the man departed Bangladesh on Aug. 30 and traveled to Istanbul in Turkey as his final destination, via Delhi and Abu Dhabi.

Several of the suspects in the bombing case are believed to be Turkish.
