Nattapol Kemngern, 22, a musician and artist for a movie set, confessed that on May 24, he had used black paint to form the letter “A” with a circle around it in two spots on May 24.
The court convicted him for violating Article 360 of the Criminal Code and several articles of the Public Cleanliness and Order Act.
The judge handed him a sentence of two years in prison, but commuted it to one year, citing his cooperation. The defendant was remanded after no one moved for his release on bail.
