Jamie Harron, a 27-year-old electrician from Stirling, was arrested for public indecency after he touched another man in a bar, apparently to avoid spilling a drink.
The incident took place at the Rock Bottom Bar on July 15.
The man who had accused him of touching his hip last week reportedly dropped his complaint against Harron and it was believed that he might be sent home soon.
But this weekend, Harron was jailed for three months after spending months in jail and thousands of pounds on legal costs and expenses.
Detained in Dubai, a legal advocacy group, confirmed today that Harron was jailed for three months but that they planned to appeal the decision.
According to the group, Harron said he was “angry, disappointed, and dreads what may happen next”.
Harron remains out of custody while the appeal is considered, Radha Stirling, DiD’s chief executive said.
Ms Stirling said: “Now Jamie has been sentenced to three months; there is no telling whether a judgement on appeal will be better or worse.
“He has already suffered tremendously as a result of these allegations, and now faces the likelihood of incarceration.
“His family was unable to visit him during this critical time because they faced a very real risk of imprisonment themselves under the UAE’s cybercrime laws which forbid criticism of the government.
“At this point, Jamie will definitely be pursuing civil action against his accusers when he does eventually return home, as it appears that he will not be able to find justice in the UAE.”
