DSI director-general Tarit Pengdith said Amphorn Jaikorn was implicated in a previous explosion at an apartment in Nonthaburi in 2010, during the red-shirt protests in Bangkok. This time, she had only been detained and questioned by police about her alleged role in the Min Buri incident that killed two men on a motorcycle carrying a pipe bomb, he said.
Tarit explained that she was released on a Bt400,000 bail guarantee as there was a lack of evidence.
