The first incident occurred at approximately 2:18am at the Birds Cafe Restaurant in Soi OrBorTor, Cherng Talay.
According to Kochem Nukun, a 68-year-old security guard at the restaurant, a foreign man arrived on a motorbike, parked in front of the establishment and proceeded to break the glass windows.
The sound was loud enough to resemble a gunshot, prompting fears that a firearm had been used. The perpetrator quickly fled the scene on his motorcycle.
Less than an hour later, at around 2:58am, a second foreign man arrived and smashed more glass at the restaurant before fleeing in a similar manner.
Police are now working to identify and apprehend the suspects, and confirm the motives behind the attacks.
