Bangkok, Sep 7 (IANS): The latest suspect caught in connection with deadly Bangkok blast has admitted to assembling the bomb before handing it to a yellow-shirted suspect who subsequently planted the device at the location, the media reported on Monday.

Yusufu Mieraili, 25, whose nationality was yet to be confirmed, was apprehended on September 1 in connection with the August 17 blast at Erawan shrine in Bangkok.

He had been ordered by the mastermind, identified as "Izaan", to buy bomb-making materials from the internet, Xinhua news agency reported.

Having finished making the bomb, the suspect was ordered by Izaan to give the bomb to the yellow-shirted man.

According to the suspect, Izaan left Thailand on August 16. He had also commanded the yellow-shirted bomber and a blue-shirted man suspected to have dropped a bomb at the Sathorn pier on August 18.
