Metropolitan Police Bureau chief Sriwara Rangsipramanakul led a team of bomb disposal police, forensic officers and soldiers in the search of Oud dormitory in Din Daeng district of Bangkok on Sunday following a raid on an apartment in Phra Khanong on Friday night.
Authorities have obtained information that some tenants at the Din Daeng dormitory had links to the Aug 17 Erawan shrine blast and the Sathon pier explosion.
The four-story female dormitory has 24 rooms. Officers searched room No 104 and seized travel bags and computers for DNA examination and traces of fingerprints to see whether they matched DNA samples of those involved in the bomb attacks.
A source said two university students rented the room. Two months ago, a mother of one of the two students had reportedly brought a middle-aged woman to stay in the room by claiming that she was her friend.
