Thai police have arrested the ‘Turkish national’ Adem Karadag as a suspect in a bombing that killed 20 people and wounded more than 120 at the revered Erawan Shrine in Bangkok on 17 August.

Thai police raided an apartment in Nong Chok suburbs of Bangkok, a district with a large muslim population, and discovered possible bomb-making materials and a number of fake passports.

Adem Karadag is thought to resemble the suspect captured on CCTV cameras leaving a backpack at the site moments before the deadly explosion.

Royal Thai Police spokesman Pol Lt Gen Prawut Thavornsiri said that the detained man is a foreigner using a fake Turkish passport and his nationality is not confirmed. Police also said the detained is part of a network but the attack is unlikely to be linked to international terrorism.

The deadly bomb attack at Ratchaprasong was a personal revenge for his friends and relatives who were deported by Thai authorities recently, Thai PBS reported.
