"We got a message from Thai police that Bangkok blast suspect Abudureheman Abdusataer, also known as Izan, came to Bangladesh. He was travelling on a Chinese passport," national police spokesman Nazrul Islam told AFP.
"We verified the message and found that he came to Dhaka on the Biman Bangladesh Airlines flight No. BG0089 and flew out to Beijing on August 30 on a Jet Airways flight," he said.
Thai local media reports have focused in recent days on a suspected bomb mastermind known as "Izan" or "Ishan", saying he commissioned and guided the attack but left the country a day before it was carried out.
Thai police confirmed today that the man was a suspect but played down his status, however.
"Do not conclude Ishan was a big fish," Thai police chief Somyot Poompanmoung said. "You might be surprised."
Mystery still surrounds the motive of the group accused of being behind the August 17 bombing that left 20 people dead in the heart of Bangkok and rocked Thailand's tourist industry.
