Yan Marchal, who posted a video mocking the now-dissolved National Council for Peace and Order (NCPO) in 2019, returned to Phuket from France. He was told by immigration officials that he was prohibited from entering because he was deemed a threat to national security, reports the Bangkok Post.
He said he was also served a legal notice saying his behaviour indicated he was a possible danger to the public.
According to the legal notice, Mr Marchal will be expelled in accordance with the Immigration Act though he can lodge an appeal within 48 hours.
Mr Marchal said he intended to appeal the ban. However, he said he could not contact the French embassy for advice.
Pol Maj Gen Achayon Kraithong, deputy commissioner of the Immigration Bureau, said yesterday that the Frenchman is on the blacklist of several agencies and immigration officials decide to not grant him entry.
He said Mr Marchal was flown from Phuket to Suvarnabhumi for the deportation process.
Mr Marchal, who has lived in Thailand for 18 years, was quoted as saying that Thailand is his home and that he has a Thai wife, two children and a business here. He was also quoted as saying that the re-entry ban was likely linked to his social media posts involving Thai politics.
The Frenchman shot to fame when he posted a brief clip ridiculing an NCPO song in 2019. The video had over 1 million views overnight before police asked him to take it down.
Mr Marchal is known to share his political views on Facebook and he has recently turned to TikTok to make fun of politics and already gained a solid following of 600,000.
