The UAE Attorney General said several arrests were made after footage of a rape was shared on social media.
Hamad Saif Al Shamsi said video showed a group of "young men raping a girl", which was posted on various platforms.
"Urgent investigations were conducted to discover the details of the incident, the people who did it, when and where it happened," a statement on state news agency Wam read.
"Investigators were very quick to discover all factors, and an arrest warrant was issued to summon the accused."
He said arrests were made on Wednesday.
He did not specify the number of suspects, their nationalities or details regarding their background.
"They are currently being questioned and thoroughly investigated," he said.
No details of the suspected victim or her age were released.
Officials said details were made public because of "severity and gravity" of the crime, although they stressed that such incidents were rare.

Stuck in a job without a pay rise? Here's what to do
Chris Greaves, the managing director of Hays Gulf Region, says those without a pay rise for an extended period must start asking questions – both of themselves and their employer.
“First, are they happy with that or do they want more?” he says. “Job-seeking is a time-consuming, frustrating and long-winded affair so are they prepared to put themselves through that rigmarole? Before they consider that, they must ask their employer what is happening.”
Most employees bring up pay rise queries at their annual performance appraisal and find out what the company has in store for them from a career perspective.
Those with no formal appraisal system, Mr Greaves says, should ask HR or their line manager for an assessment.
“You want to find out how they value your contribution and where your job could go,” he says. “You’ve got to be brave enough to ask some questions and if you don’t like the answers then you have to develop a strategy or change jobs if you are prepared to go through the job-seeking process.”
For those that do reach the salary negotiation with their current employer, Mr Greaves says there is no point in asking for less than 5 per cent.
“However, this can only really have any chance of success if you can identify where you add value to the business (preferably you can put a monetary value on it), or you can point to a sustained contribution above the call of duty or to other achievements you think your employer will value.”
