The family of a Singaporean man jailed with a transgender friend in the United Arab Emirates for dressing in a "feminine" way called Friday for their release, as activists raced to raise funds for legal fees.

Fashion photographer Muhammad Fadli bin Abdul Rahman and transgender friend Noor Vitriya Kistina Ibrahim were arrested at a shopping mall in Abu Dhabi at the weekend and sentenced to a year in jail, according to relatives.

Fadli's brother Saiful told AFP from Singapore that the pair were detained by the tourism police for "looking feminine".

Advocacy group Detained in Dubai said they were convicted of charges related to "inappropriate behaviour over their clothing". The group confirmed both were sentenced to a year in jail.

Fadli, 26, told his family that he was wearing earrings and a tie at the time of his arrest, Saiful added.

"We want them released and back to Singapore as soon as possible," he said, adding his brother was a "friendly, happy-go-lucky and jovial person."

"We were informed that he was arrested for looking feminine, but looking feminine is very broad. It was emotional, my parents broke down when they heard the news," he added.

Singapore's foreign ministry said officials from the city-state had met with the pair four times since their detention and were providing consular assistance.

However, the ministry also reminded citizens to "respect and abide by the local laws when they travel overseas".

Rights activists in Singapore launched an online crowd-funding campaign to raise Sg$25,000 (US$18,000) for their legal and other fees and reached their target just after midday Friday, according to their Facebook page.

The money has been sent to a law firm in Abu Dhabi, the activists said.

Noor is described by activists as a transgender person who has not yet undergone sex change surgery to become a woman.

Radha Stirling, head of London-based advocacy group Detained in Dubai and managing partner at the Stirling Haigh law firm, said Thursday her organisation will appeal the verdict and request the sentence be reduced to a fine and deportation.

The United Arab Emirates criminalises sodomy, as well as both pre-marital and extra-marital sex.

Article 358 of the penal code also criminalises "indecent attire" as an act of public indecency.
