Police in Thailand say relatives of a woman whose arrest they are seeking in connection with the deadly Aug. 17 bombing at a central Bangkok landmark have told them they believe she is in Turkey, Time reports.

Police issued an arrest warrant for the woman Monday, August 31, identified as Wanna Suansun, who was listed as having rented an apartment where bomb-making materials were found by authorities. Police raided the woman’s registered residence in the southern province of Phang Nga, but did not find her.

Police Maj. Gen Chalit Keawyarat said her relatives told them she had been away for three months, and they believed she was in Turkey because her husband is Turkish.

On 17 August 2015, a bombing took place inside the Erawan Shrine at the Ratchaprasong intersection in Pathum Wan District, Bangkok, Thailand, killing 20 people and injuring 125. Surveillance footage showed a suspect leaving a backpack at the scene shortly before the explosion.
