The National Council for Peace and Order (NCPO) has confirmed security alerts in greater Bangkok late this month and ordered checkpoints be set up and searches conducted.
NCPO spokesman Piyapong Klinphan said on Tuesday that the council ordered relevant organisations to be vigilant for suspicious movements, set up checkpoints and conduct searches to prevent untoward incidents.
October was a politically significant month and government officials must ensure public safety and prepare themselves for any situation, Col Piyapong said, referring to police's warning of possible violence from Oct 25-30.
Authorities are monitoring movements of the people suspected of launching serial bombings in seven southern and central provinces on Aug 12, the NCPO spokesman said.
Prime Minister Prayut Chan-o-cha said on Tuesday that he was verifying the warning and reporters should not exaggerate it.
