National police spokesman Prawut Thavornsiri said police found items including a "suspicious fluid in a barrel" during the raid today at a home in the outskirts of Bangkok. He said the items were being examined by a police explosives unit.
Thai authorities have suggested that at least two of the eight suspects are possibly Turkish, prompting the Turkish Embassy in Bangkok to issue a statement today saying that it has not received confirmation from Thai authorities about the nationalities of the suspects.
Uighurs (pronounced WEE-gurs) are related to Turks, and Turkey is home to a large Uighur community. The bombed site, the Erawan Shrine, is especially popular with Chinese tourists, feeding the speculation that it could have been targeted by people who believe the Uighurs are oppressed by China's government.
China has alleged that the repatriated Uighurs included some who intended to join Islamic State fighters in Syria.
The passport indicated he was from the western Chinese region of Xinjiang, but Thai authorities had not yet verified its authenticity, said national police spokesman Prawut Thavornsiri. Xinjiang is the home of the Turkish-speaking Uighurs.
Authorities today identified the suspect but issued two different spellings of his name Mieraili Yusufu and Yusufu Meerailee and said he faces charges of possessing unauthorized explosives.
Police said they found his fingerprints on a bottle of bomb-making material recovered from an apartment that was raided over the weekend.
The home police raided today was leased by Wanna, the police spokesman said.
