Ms Yingluck arrived at the Royal Thai Army auditorium about noon to report to the NCPO.
Her move was in response to the NCPO’s order that 114 additional persons, including Thailand's first woman premier, have to report to the council.
Prior to Ms Yingluck's arrival, key figures and former cabinet members appeared at the Royal Thai Army auditorium.
Those reporting to the NCPO in the morning included former acting caretaker premier Niwatthamrong Boonsongphaisan, former foreign minister Surapong Tovichakchaikul, former energy minister Pongsak Raktapongpaisal and former deputy prime minister Plodprasop Suraswadi.
Meanwhile, People's Democratic Reform Committee leaders including Anchalee Phaireerak, Buddhipongse Punnakanta, Chumpol Julasai, Nathapol Teepsuwan and Taya Teepsuwan also reported to the NCPO.
In addition, former prime minister Somchai Wongsawat and his wife Yaowapa, who is a younger sister of ousted premier Thaksin Shinwatra, reported to the council.
In a related development, the NCPO announced that 155 persons the council wants to report are not allowed to leave the Kingdom, without permission from the NCPO chief.
Those who do not report to the NCPO will be looked for and arrested for further prosecution when found.
To create better understanding about the current situation among foreign countries, the NCPO invited all foreign diplomats, representatives of international organizations to attend meeting at 4pm at the Army Club on Vibhavadi Rangsit Road.
