A German who was arrested for a string of attacks on dentists has been found dead in his home in Thailand.

Matthias Ebner, 41, was discovered with a gruesome neck wound at his residence in Nakhon Ratchasima province, on March 21. Police had previously arrested him on March 18 on assault charges, but released him on bail just a day later.

The grisly scene was discovered when Matthias's Thai wife, who was away in another province, became concerned after he failed to answer her calls. The worried spouse asked a neighbour to check on the German.

Upon arriving at the property, the local peeked through the glass doors and found the house in disarray. When no one responded at the door, he then looked through the transparent bedroom windows and found the dead German lying on his bloodstained bed with a huge wound on his neck.

Police arrived at the home to collect evidence. They had to call animal control officers as two pet Rottweilers were guarding Matthias's corpse.

A police spokesman said: 'We are considering two possible causes for his death: suicide or homicide. Police are reviewing CCTV footage from inside and around the house to gather more evidence.'

Authorities said they have notified Matthias's wife of his death.

The expat had been arrested by police for a series of attacks on dentists in Nakhon Ratchasima.

Shocking CCTV footage showed him striding past staff to barge into the woman's quarters on March 14. The terrified dentist was seen fleeing as security guards arrived to control the German.

A separate clip from a different incident in November 2024 shows him blowing up at yet another female dentist, threatening 'I'll kill you' as the locals urged him to calm down. He was said to have bitten her lip and bashed her head against the wall.

The violent German was said to have gone on rampages in at least six different clinics, and even sent death threats to the dentists through their social media accounts. Helpless locals had slammed the police for their alleged inaction, before Matthias was nabbed on March 18.

His Thai wife said he had been receiving psychiatric treatment in Germany before being fired 'for erratic behaviour' at his workplace. He then moved to Thailand and began taking cannabis - now legal in the country - as self-medication.

Immigration officials were in the process of revoking his visa before he was found dead.

Cannabis with under 0.2 per cent of THC was decriminalised in Thailand in June 2022, as a potential cash crop for impoverished farmers. Cannabis smoking is allowed for personal use in private areas but remains prohibited in public spaces.

However, bungling officials are now seeking to outlaw recreational cannabis, blaming poorly regulated use for allegedly fuelling drug abuse and a rise in the the number of cases of tourists over-indulging in the drug.

Tourist destinations such as Bangkok, Phuket and Pattaya have seen the negative consequences of legalising the drug, with tourists regularly arrested for misbehaving while under the influence of cannabis.

Earlier in January, Russian father Artem Bugorskiy, 45, allegedly threw his son overboard on a ferry while he was high on cannabis in Phuket. The teenager was killed by the boat's propeller.
