Gen Prayuth set up a meeting with all regional army leaders at the 1st Infantry Regiment (Royal Guard) on Vibhavadi Rangsit Road to assess the situation and "adjust military deployment" after reports of violence, military sources told the Bangkok Post.
He cancelled an earlier plan to attend celebrations of the First Army Region Day at its base on Monday. Lt Gen Theerachai Nakwanich was assigned to preside at the event in Gen Prayuth's place.
The meeting was called after gunmen fired at the headquarters building of the Democrat Party at 2.30am on Monday. No one was injured in the shooting, which damaged a party-owned coffee shop.
A man believed to be an anti-government protester was wounded by a gunshot near a blockade of the People's Democratic Reform Committee (PDRC) on Vibhavadi Rangsit Road just before midnight on Sunday.
