Thai police have said a second suspect arrested in connection with last month’s deadly bombing at a Bangkok shrine was carrying a piece of paper with a chemical formula used to make explosives written on it.
Speaking Thursday, National Police spokesman Prawut Thavonsiri said they believe the formula is based on acetone, a volatile and flammable substance.
“These mix of chemicals you can easily obtain anywhere legally, but when you combine them, they become a chemical that is quick to catch fire and can be developed to become a detonator,” he said.
“This formula can also be used to enlarge the radius of the bomb. It could be used for both of the bombings. But when the bomb detonates, this element (if used in the bomb) would disappear immediately because it’s an amplifier.”
On Wednesday police revealed that fingerprints taken from possible bomb-making material found at an apartment in Bangkok at the weekend, match those from this same suspect, who was apprehended on Tuesday trying to cross the border into Cambodia.
While his identity has not been revealed, police say the man was sharing an apartment with another male arrested during the weekend raids in the capital.
Chief suspect?
Police believe both men are foreigners and had been traveling on false documents. National Police General Chakthip Chaijinda said at a briefing Wednesday that the second suspect spoke Turkish and the interrogation was conducted through a translator.
He added that they are still trying to determine whether he is the man pictured on surveillance video wearing a yellow T-shirt and dark-framed glasses minutes before the bombing at the Erawan shrine. Police believe this man is the chief suspect in the attack.
In a televised address also Wednesday, Prawut said the second suspect may have carried the bomb, or placed the bomb at the shrine, that killed 20 people and injured numerous others on August 17.
However police have asked for more time to determine his exact role in the atrocity.
New name revealed
Meanwhile, another suspect in the shrine attack has been named by police.
An arrest warrant has been issued for Emrah Davutoglu, the husband of a previously named suspect, on suspicion of organizing and providing accommodation to other suspects, Thailand national police spokesman Prawut Thavornsiri said.
Davutoglu and his wife, Wanna Suansan, 26, of Thailand are believed to have left the country at the same time, Prawut said, without elaborating on the timetable or their whereabouts.
Thai police previously said Wanna’s husband is Turkish. But Prawut did not comment Wednesday on Davutoglu’s citizenship.
Davutoglu and Wanna are among eight people for whom Thai police have issued arrest warrants in connection with the bombing, Prawut said.
Second weekend raid
Thai police said this week that they were looking for Wanna after authorities found bomb-making materials Sunday in a Bangkok-area apartment — the second they raided — allegedly connected to her.
Her mother told police that she left Thailand two months ago “to stay with her husband in Turkey,” police Col. Saharat Saksilapachai said Monday.
Wanna has contacted Thai police through social media and denied any involvement, police said. She admitted renting a room in an apartment in Bangkok, though she said she gave it up almost a year ago, according to police.
She said she’s in Turkey with her baby and husband, according to Saharat.
Authorities said Wednesday that Wanna is considering whether she to return to Thailand to face accusations.
When Thai police announced Monday they were seeking Wanna, they released a sketch of an unidentified man, with dark hair and a mustache, whom they are also looking for in the case. Police said Monday that the man was not Wanna’s husband but did not reveal much else about him.
