The man Thai police believe masterminded deadly Bangkok bombing in August fled to Bangladesh the day before the attack and travelled on a Chinese passport, officials said on Wednesday.

The man emerged as a key suspect in the August 17 bombing following interrogation this week of one of two foreigners being held, who police say admitted to giving a backpack with explosives to a man they are certain was the bomber.

The suspect told police a man called “Izan” played a lead role and assigned responsibilities to others plotters during a Bangkok meeting. “This man called Izan – and I don’t know if this is his real name – is a very important person in this network,” deputy police chief Chakthip Chaijinda said.

“I don’t know what his nationality is … Let’s just say Izan is one of the foremost wanted individuals.”

No group has claimed responsibility for the blast at the Erawan Shrine, which killed 21 people, including 14 foreign tourists.

Mr. Chakthip said police would be coordinating with Bangladeshi counterparts where the suspected leader had travelled on August 16. An immigration official said he had used a Chinese passport, but it was not known if it was authentic.

A.K.M. Shahidul Hoque, inspector general of Bangladesh police said that he was unaware of the new development. (The Hindu)
