Two Foreign Tourists Spray-Paint School Fence in Chiang Mai — Arrested and Fined, Stoking Community Concern

On 12 July 2026, two foreign tourists were detained by Chiang Mai police and fined after members of the public reported suspicious persons spray-painting a school fence and public property in a neighborhood in downtown Chiang Mai. The incident was posted on the Chiang Mai Provincial Police Facebook page and sparked alarm and anger among parents and local residents.

The incident began around midday when a resident saw a suspicious person holding a spray-paint can and spraying a school fence before running away. Officers were notified and were able to apprehend the two tourists as they tried to flee near the scene. Police said the suspects were two young foreign tourists traveling with a group. After their arrest the two admitted to the spray-painting and were charged with causing damage to property and vandalizing public property; they also paid fines and compensation as requested by the school.

Teachers and parents said the fence and walls that were painted require repair and cleaning, and the school must use donated funds and its regular budget to restore the area. Some of the paint markings fell onto children’s play areas, causing parents to worry about safety and the appropriateness of certain tourists visiting community educational spaces. The school administration has coordinated with local authorities to strengthen preventive measures to avoid a repeat of such incidents.

The case also highlights tensions between growing tourism and the desire to preserve Chiang Mai’s traditional community spaces. The city center, which includes residential neighborhoods, schools, and public areas, often faces tourist behavior that disregards local customs and property. Even a seemingly minor act like spray-painting can be seen as disrespectful to public spaces and harm the city’s tourism image, which heavily depends on visitor income.

Chiang Mai police commented that although the offenders were foreign tourists, anyone who breaks the law in Thailand must accept legal consequences. Police emphasized cooperation with tourism agencies and communities to run campaigns educating tourists about laws and proper conduct, as well as installing CCTV and increasing patrols in areas prone to such incidents.

Tourists and tourism operators in Chiang Mai said they want more proactive measures, including providing information before visitors enter sensitive areas, posting warning signs, and running awareness campaigns about conserving public spaces and respecting communities. Shop owners near the school suggested coordinating with local tourism business associations to organize awareness activities and urged authorities to impose clear penalties and provide concrete reparations to prevent repeat offenses.

The incident serves as a reminder to both visitors and host communities that sustainable tourism requires mutual respect and shared responsibility. Chiang Mai, with its cultural charm and local communities, must find a balance between welcoming tourists and preserving residents’ quality of life so tourism benefits everyone in a sustainable way.
