The president of Italian-Thai Development Pcl, Thailand's largest construction company, pleaded not guilty on Wednesday to trespassing in a wildlife sanctuary and poaching, a lawyer said.
Premchai Karnasuta and three company employees were arrested in February for allegedly poaching protected animals in the Thungyai Naresuan Wildlife Sanctuary in the western province of Kanchanaburi.
Several carcasses of protected animals including a black Indochinese leopard were found near their jungle campsite, national park rangers had said.
