A nightclub owner and a lighting effects company executive have been sentenced to three years' imprisonment each for a fire that killed 67 people in the Thai capital on New Year's Day 2009.
The Bangkok Criminal Court found Santika nightclub owner Wisuk Sejsawat and company executive Boonchu Laosinart guilty of causing the deaths of other persons without intent.
More than 1,000 revellers were inside the club when an indoor fireworks display set off after the countdown to New Year ignited the blaze. More than 100 people were injured.
The court also ordered Boonchu's company to pay 8.7 million baht (£162,000) in compensation to the victims or their families.
Four other people were acquitted.
