Almost 23,000 CCTV cameras have been installed in Bangkok and surrounding provinces ahead of the Asia-Pacific Economic Cooperation (Apec) summit.
The figure is according to national police chief Pol Gen Damrongsak Kittiprapas, who said he chaired a joint meeting on Thursday with more than 30 agencies to further address security and traffic measures related to Apec.
The summit takes place today and tomorrow. A total of 17,848 CCTVs across Bangkok and another 5,000 in Nonthaburi, Pathum Thani and Samut Prakan have been installed, he said.
More than 35,000 police are being deployed to oversee checkpoints along routes leading to the summit's venue, the Queen Sirikit National Convention Center, and hotels where Apec leaders are staying.
Advanced communication and security technologies are being deployed in the operation, Pol Gen Damrongsak said.
Pol Gen Roy Ingkapairoj, deputy national chief, on Thursday checked the readiness of the monitoring and information administration centre at the Central Investigation Bureau (CIB).
He said the centre will verify security information on wanted criminals, suspicious individuals, vehicles, routes and more, using the CCTV cameras installed.
Meanwhile, a protest group confronted riot control police outside Terminal 21 shopping mall on Sukhumvit Road on Thursday. About 100 protesters gathered to stage a rally called "What's happening in Thailand?".
Some carried placards calling for the expulsion of Prime Minister Prayut Chan-o-cha, while others had signs saying "Free Hong Kong".
