No its based on facts here is the printout from thai embassy website. I hope this helps. "What the law says. Thailand’s Immigration Act turns people away if they’ve been imprisoned by the judgment of a Thai or foreign court, other than for a petty offence, a negligence offence or an offence exempted by ministerial regulation. An arrest without a conviction isn’t a sentence, so you’re not in that group. Even people who do have a record aren’t automatically denied. The Thai embassy or consulate handling the application makes the final decision, and may ask for more information or documents"
