NAKHON RATCHASIMA — Following criticism for allowing the case to stall, Nakhon Ratchasima Provincial Police have finally taken action. They arrested the German man living in Thailand who allegedly trespassed and vandalized at least six dental clinics in the city center and assaulted at least two dentists.
On the evening of March 18, Police officers arrested Mr. Matthias, a 41-year-old German national, at the parking lot of Klang Villa Department Store in Mueang District, Nakhon Ratchasima Province. He was apprehended while sitting in the back of a pickup truck.
The suspect was subsequently taken to Jor Hor Police Station, where authorities arranged for an interpreter to assist with questioning and to prepare the arrest record. He faces three charges: trespassing, assault, and property damage.
Police expedited their actions after this case appeared in media reports for just one day, despite dragging on for several months. They immediately requested an arrest warrant from the court and then proceeded to the suspect’s residence in Ban Don Chomphu, Don Chomphu Sub-district, Non Sung District, Nakhon Ratchasima. However, the suspect fled by car before police arrived.
His Thai wife has reportedly already fled to Chonburi Province, unable to tolerate her husband’s behavior.
According to the man’s wife, he has a history of psychiatric treatment in Germany and was dismissed from his job due to mental health issues before moving to Thailand to live with her. Since then, he has refused treatment or medication for his condition, opting instead to use cannabis.
Police Colonel Kachen apologized to dentists in Jo Ho Sub-district and Muang Nakhon Ratchasima District who have been affected. In a case from November 30, 2024, reported at Jo Ho Police Station, the suspect allegedly assaulted a female dentist by banging her head and biting her lip. Police had already issued two summonses for him to acknowledge the charges, but he refused to meet with investigators.
Regarding two subsequent incidents at dental clinics in Muang Nakhon Ratchasima District that were reported to the Muang Nakhon Ratchasima Police Station, the victims declined to press charges due to the suspect’s history of mental health treatment, so no summonses were issued.
The most recent incident occurred on March 14, 2025, when he stormed into a downtown clinic, furiously verbally abusing a dentist until the terrified female dentist had to flee to safety.
The Nakhon Ratchasima Dental Association has issued warnings to dental clinics across the province to be vigilant about this dangerous individual.
