Iranian police cracked down on more than 500 restaurants for not observing “Islamic principles” including modesty announced the police chief. “The owners of restaurants and cafes in which Islamic principles were not observed were confronted, and during this operation 547 businesses were closed and 11 offenders arrested,” Hossein Rahimi said in statement Saturday, as AFP reported.

Some of the violations include “unconventional advertising in cyberspace, playing illegal music and debauchery.”

Tehran citizens were encouraged on Saturday to report cases of “immoral behavior” by texting a specific phone number set up to respond to these crimes. The head of Tehran’s guidance court, which deals with “cultural crimes and social and moral corruption,” made the request for people to report the violations.

“We decided to accelerate dealing with instances of public immoral acts,” Mohammad Mehdi Hajmohammadi reportedly told the judiciary’s Mizan Online.

Other problematic behavior included removing a “hijab in cars,” “hosting mixed dance parties” and posting “immoral content on Instagram.”

In 2012, the government demanded cafes and restaurants install cameras to monitor the behavior of customers. Some chose to close rather than install the cameras.

“As much as it pains us and as much as we will miss our friends and all of you who stood by our side in the past four years, we take comfort in knowing that we at least didn’t let Big Brother’s glass eyes scan and record our every step, minute and memory from dawn till dusk,” wrote the owners of the popular Cafe Prague at the time.
