-The Dubai Code of Conduct says dancing and loud music is forbidden in public places, such as beaches, parks and residential areas. It is classed as "indecent and provocative".
-It is against Dubai law to live together, or to share the same hotel room, with someone of the opposite sex if you aren't married or closely related, according to Foreign Office guidance. So, in theory, any unmarried couple staying in a hotel room together is breaking the law.
-Taking pictures of women in public without consent is "strictly frowned upon", as is randomly addressing women in public, the Foreign Office states. Showing any disrespect towards religious beliefs or practices is considered deeply offensive and very likely to result in a heavy fine or imprisonment.
-Non-repayment of debt is a criminal offence and can get people sent straight to jail. Having a check bounce and not paying bills - including a hotel bill - can also result in imprisonment.
-Bringing some medicines into the country is also forbidden, including some containing psychotropic substances. The Foreign Office says if you are using prescribed drugs it is advisable to carry a doctor's note and you may need to seek prior agreement from the authorities.
-Rape is illegal in Dubai of course. However, alleged victims have also occasionally found themselves facing arrest.
In 2013, Norwegian woman Marte Deborah Dalelv said she had been raped by a colleague while on a business trip in Dubai. She reported the attack to the police, but was charged with having extra-marital sex, drinking alcohol illegally and perjury after prosecutors dismissed her rape allegation.
-Kissing and hugging in public are strictly prohibited.
