Thai police have sought help from Bangladesh through Interpol to help locate the mastermind behind the fatal bomb blast after investigations indicated that he might have fled to this South Asian country.
Designated police chief Pol Gen Chakthip Chaijinda said that the information about the possible whereabouts of Abu Dustar Abdulrahman or Izan, a Chinese national, had been confirmed through evidence and testimony from witnesses.
"We have already asked Interpol to inform Bangladesh about the latest development concerning the mastermind behind the bomb blast at the Erawan Shrine," said Chakthip who will become police chief next month.
He said without elaborating that police were tracing money channelled from foreign countries to see whether it was used in funding the attacks.
Referring to the yellowshirt man who is suspected of being the bomber, he said that police are confident that he would be arrested based on the information and evidence they have in hand.
