Pratew Mansap, 38, at Ayutthaya Atlantic, was found in possession of seven large planks of Takian Sai wood. Takien Sai (Shorea gratissima) is listed as an endangered species by the UN-affiliated International Union for the Conservation of Nature.
At the Underwood factory another nine large pieces of the same timber were found, totalling 7.01 cu m.
Neither the Underwood factory nor Ms Pratew was able to produce the correct paperwork, the officers alleged.
Investigators are now attempting to get more details of the timber’s origins.
