Police yesterday took custody of a key suspect - accused of involvement in the grenade attack on the Criminal Court - from the military.
The woman was then charged with terrorism and criminal conspiracy for her alleged roles in the March 7 attack and also allegedly planning attacks on four other locations in Bangkok.
Natthathida Meewangpla, or Waen, was reported to have been taken away by military officials on March 11, according to a human rights group.
Free Thai Legal Aid coordinator Winyat Chartmontree said on the FTLA Facebook page that two uniformed Army officers and three others in plain clothes were seen entering her Samut Prakan home and taking the former volunteer nurse away.
On Monday the National Council for Peace and Order and Army spokesman Colonel Winthai Suvari denied that the military had apprehended or detained Natthathida. However, yesterday he was forced to backtrack on that.
First Army Area commander Lt-General Kampanart Ruddit said the apprehension and questioning of high-profile suspects was conducted secretly in accordance with martial law.
But he said all suspects would be processed openly once police take over their cases, with evidence from the military.
Kampanart said all actions of the military had not been reported to him, as commander of the military's security force. That was why Winthai made the denial about Natthathida on Monday.
A senior police investigator, Major General Chaiyaphol Chatchaidej, accused Natthathida of seeking people to do five attacks through a suspect - Suraphol Iamsuwan - as well as deciding on the locations for each attack, at a price of Bt10,000 (S$421) for each.
The grenade attack at the Criminal Court on March 7 was the second, but number four among five targets chosen under the plan.
A second pair of attackers was recruited and contacted by another suspect, Wirasak Towongjorn, an alias for 'Yai Pattaya', who is on the run, the officer said.
FTLA officer Winyat said yesterday that Natthathida was a key witness in the fatal shooting of six people in Wat Pathum Wanaram temple after the military dispersed the red shirts' protest in Bangkok on May 19, 2010.
Her disappearance, albeit brief, was an obstruction to the ongoing trial over the temple shootings.
He called on the NCPO to do things in a straightforward manner, saying that apprehending Waen or any| citizens without notification to relatives was violated people's rights.
Separately, the Criminal Court yesterday handed a five-month prison term for contempt of court to motorcycle rider Mahahin Khunthong and grenade-thrower Yutthana Yenphinyo. who were arrested by soldiers shortly after carrying out the Criminal Court attack.
The two men were among 16 suspects accused of related crimes. This includes three still on the run.
