Chuvit Kamolvisit, 55, and 65 others were sentenced to two years in jail each without suspension by the Supreme Court Thursday for the demolition of bars and shops on a Sukhumvit Square night strip in 2003.
In late 2005, the land was turned into Chuvit Park, a public park personally funded by Chuvit.
Chuvit said he had bought the land in 2002 and planned to build a four-star hotel there but had problems with existing tenants.
