They were just looking to cool off and have a little fun in the middle of Tehran's scorching-hot summer.
Instead, a group of young Iranians got all tangled up with authorities in the Islamic Republic and paraded on Iranian state television for participating in a mass public water pistol fight in a Tehran park, Iranian media reports say.
On Wednesday night, state channel broadcast images of some youth who were arrested at the event on July 29, the Iranian daily Assre-Iran reported.
They said in the program that they had chatted with each other on Facebook and decided to meet at the park -- ironically named Tehran's Water and Fire park -- at that date with water guns, added the report.
The event reportedly attracted about 800 people through a Facebook invitation.
