Leena Jungjanja, the owner of the Hot TV shopping channel and perennial Bangkok governor candidate, was barred from entering the National Reform Council (NRC) kickoff event on Saturday morning.
Ms Leena complains after she was not allowed to enter the NRC kickoff event on Saturday.
Ms Leena, whose TV channel has been banned by the junta since the May 22 coup, wanted to attend the event and propose herself as an NRC candidate.
However, the military did not let her in and detained her in a reserved area at the Royal Thai Army Club where the event was held.
She was allowed to enter only after Gen Prayuth Chan-ocha, chief of the National Council for Peace and Order (NCPO), finished his speech and left.
She also brought with her a letter complaining about what she views as an unfair signal fee. A military officer accepted her complaint.
"I want to be an NRC member and will apply to the Election Commission on Aug 14 so I can get a fixed salary. After all, my business is losing money because of the NCPO ban," she said.
Ms Leena on Aug 2 posted a widely watched and hilarious video clip slamming Gen Prayuth for shutting down her TV channel, claiming she was being starved to death.
