The Thai Interpol has sought cooperation from its counterparts in 190 countries to help track down former prime minister Yingluck Shinawatra, said Pol Gen Srivara Rangsipromnakul on Monday.
Meanwhile, Prime Minister Prayut Chan-ocha admitted security lapse for Ms Yingluck's successful exit without the notice of security officials, but he begged critics and members of the public not to blame the officials, claiming that this has happened before on various occasions.
He admitted that he had no idea about which channel that Ms Yingluck managed to sneak out of the country without being noticed.
He noted that Thailand has more than 5,000 kilometre long natural borderline with neighbouring countries and it is difficult for officials concerned to monitor the long borderline 100 percent.
The prime minister, however, said he had instructed the Foreign Ministry to coordinate with foreign governments to help locate the whereabouts of Ms Yingluck who was reported to plan to seek political asylum in Britain.
Pol Gen Srivara on Monday held a meeting with senior police officers to discuss the whereabouts of Ms Yingluck and how to locate her.
He said the former prime minister was last seen on August 23 and he admitted that police could not watch her all the time.
He added that he had instructed police to locate Pol Col Watunyu Wittayapalothai, Yingluck's bodyguard, and to find out whether he is still in police service.
