Translation: “Urgent... The Attorney General of Saudi Arabia announced the arrest of a girl who breached the kingdom’s public decency at an event in Riyadh.”

It is unclear whether the woman will receive a fine, a prison sentence or worse, though Saudi authorities warned they would issue fines for a number of public decency offences for tourists visiting the country, including immodest dress and public displays of affection.

Violations listed include littering, spitting, queue jumping, taking photographs and videos of people without permission and playing music at prayer times, the interior ministry said.

Those caught violating the law could face fines ranging from 50 riyals ($13) to 6,000 riyals ($1,600).

The mixed-gender concert took place during the kingdom's Riyadh Season festival, running from October to December as part of the kingdom's latest projects to increase income and tourism.
