The charges included insurrection, inciting disorder or civil disobedience and creating assemblies of 10 persons or more to incite unrest in the city and refuse police orders to end their actions, DSI chief Tarit Pengdith told a news conference on Wednesday.
The 17 leaders, who excluded PDRC leader Suthep Thaugsuban, are required to report to the DSI on Dec 26 and 27.
Mr Tarit said police investigators met to discuss the arrest of Mr Suthep and concluded that the summons for the ex-Democrat MP would not be issued yet to avoid possible confrontation with the protesters. He said the decision was based on the actual situation, but he vowed authorities would proceed to eventually bring him in for interrogation.
The DSI would also seek to freeze all types of bank accounts of the protest leaders, including Mr Suthep, and two accounts opened for receiving charitable money from supporters. It would tomorrow send letters to commercial banks with which those accounts were opened, to order them to freeze the accounts and disclose statements for the previous six months.
Owners of companies, transport and shops who intentionally supported the protesters would also be summonsed for interrogation, the DSI chief added.
The leaders, who will be summonsed, are Sathit Wongnongtoey, Chumpol Julsai, Puttipong Punnakan, Isara Somchai, Witthaya Kaewparadai, Thaworn Senneam, Natthapol Teepsuwan, Akanat Promphan, Anchalee Paireerak, Nitithorn Lamlua, Uthai Yodmanee, Saemdin Lertbutr, Preecha Iamsuphan, Somkiat Pongpaibul, Yossak Kosaikanon, Supawat Supiyapanich and Somboon Thongburan.
