Nitithorn Lamlua, a protest leader and core member of the Network of Students and People for Thailand's Reform (NSPTR), told DSI officials that he only wanted to see documents used by the DSI to accuse him and other PDRC leaders, a total of 38 people, of insurrrection and in ordering the freezing of their bank accounts.
Mr Nitithorn reportedly told the officials to leave their office, saying that he only wanted justice. He also told the protesters not to damage public property.
He said he knew that Tarit Pengdit, the DSI chief, was not in the office but was now staying at the Royal Thai Police Office.
The protesters reportedly used black cloth to cover security cameras or turned their faces away from them.
