Pol Maj Gen Jirawant said the deployment was to control any rallies and any disruption by anti-coup protesters. Authorities initially planned to guard five sites, but later decided to cover 11 spots.
The 11 spots are: Victory Monument; Central Department Store at Lat Phrao; Major-Cineplex theatre at the Ratchayothin intersection; Seacon Square Department Store; Central Department Store at Bang Na; Democracy Monument; Thammasat University Tha Phrachan campus and the Temple of Emerald Buddha; Bangkok Arts and Culture Centre, Siam Paragon and Amarin Plaza; Terminal 21 Department Store; BTS skytrain stations at Chong Nonsee and Lumpuni; and Wong Wien Yai.
Traffic in these areas is to be supervised by the chiefs of the Metropolitan Police Divisions 1, 2, 4, 5, 6 and 8.
Pol Gen Somyos Phumphanmuang, a deputy police chief, said on Saturday more than 6,000 police and soldiers would be deployed at all possible rally sites.
They would also be deployed at all BTS skytrain stations as well as on all skytrains, he said.
As of noon on Sunday, there were no reports of protesters showing up at the sites. The protests were expected to begin at 2pm.
