Prawit urged the public to be patient as the police are now looking into the facts to see whether those involved had broken the law.
At this point, three police officers who allegedly helped Yingluck leave the country had not been found to have broken the law, except for unlawfully using cars, Prawit said.
Police are looking into whether the accused officers had a plan ahead of Yingluck’s flight, to establish whether to lay charges against them. They are also searching for another car believed to been involved with Yingluck’s escape.
The three officers were detained for interrogation late on Thursday night after the police found evidence on CCTV cameras showing a police colonel driving in a Toyota Camry that took Yingluck from Bangkok to Sa Kaew province.
It has not yet been established whether or how she crossed the border.
