Two Indians have been taken into custody for questioning after they were seen on CCTVs talking to a foreign suspect wanted in Thailand's deadliest bombing at a temple here, while a person arrested in the case told police that the mastermind of the attack had fled the country.
The two Indians, not identified, were taken to a military camp for questioning, The Nation quoted police as saying.
"Nothing is really known so far about the Indians and it is not clear what the questioning is about," sources said.
The two Indians were staying in the room next to the one where police found bomb making materials, the paper said.
A foreigner who lived at the room and a Thai woman who rented the room for him are now wanted in the case.
Thai police is closely combing areas in search of people behind the August 17 bomb blast at the popular Erawan Brahma Shrine, which killed 20 people and injured more than 100 others.
A combined force of police and army officers on Sunday raided several apartment buildings and rented houses in Minburi district.
Coloner Wattana Yichin, deputy commander of the Metropolitan Police overseeing Minburi police station, said the raid was part of crime suppression measures as many foreigners rent apartments and houses in the area.
Police so far have issued arrest warrants against ten suspects in connection with the case.
Meanwhile, a suspect who was arrested near the Cambodia border identified as Yusufu Meralli, told military interrogators he assembled the bomb for the actual bomber, yet to be nabbed. Meralli admitted he assembled the bomb before handing it to a yellow-shirted suspect who was seen on CCTV at the shrine leaving behind a backpack which would have had the explosive device.
