The Criminal Court on Monday acquitted a man of stealing a van from the Prime Minister's Office during a 2008 People's Alliance for Democracy protest at Government House due to the lack of evidence.
Ekapol Noyngern, 32, was charged in 2013 with theft and receiving stolen property in violation of sections 83, 335 and 357 of the Criminal Code.
According to prosecutors, between Aug 26 and Dec 2, 2008, a Bangkok-registered van and two cars worth a total 3.5 million baht were stolen from Government House in Bangkok's Dusit district.
On Dec 24 that year, Mr Ekapol was seen driving the stolen van. He was arrested, but denied all charges.
Government officials were unable, at the time, to enter Government House due to the PAD blockade. After protests ended on Dec 2, officials inventoried the office's property and found a van and two cars missing.
However, prosecutors had no eyewitnesses to confirm that Mr Ekapol stole the van. Officials testified only that they filed a police complaint after Mr Ekapol was seen driving it and employees from the vehicle section told the court that the keys to the van and two cars went missing.
The court on Monday acquitted Mr Ekapol, giving him the benefit of the doubt. Puangthip Boonsanong, Mr Ekapol's lawyer, said it remained to be seen whether prosecutors would appeal. She said during the trial her client had been granted bail.
