Facebook water fight: Arrests in Iran after summer fun
Several young people have been arrested in Iran for taking part in a mass water fight.
The young women and men were detained after they were spotted throwing water at each other in Teheran's Garden of Water and Fire.
The event, organised on Facebook, had attracted an estimated 800 people.
Images from the park show groups of young people carrying colourful water guns and having fun soaking each other in the 40C heat, according to Radio Free Europe.
But when images of the event were posted online they upset the nation's conservatives. One conservative MP said the event was shameful and could spread "corruption".
Shortly later, the city's police chief Hossein Sajedina said some of those involved had been arrested.
He said participants of the water fight had been acting "abnormally" and were disobeying Islamic principles.
He warned that the police would act against anyone who disrupted "public order and security".
According to the Guardian, some of the people detained included a university student, who had not yet been released.
In Iran, under Islamic law, men and women who are not related by blood or marriage are not allowed to touch or interact beyond taking part in everyday transactions.
