March 26 (UPI) -- A Turkish mayor promised an investigation after public loudspeakers in at least one neighborhood broadcast the audio from a pornographic film.

A witness in the Kuzeykent neighborhood of Kastamonu captured video of the loudspeakers, which are normally used to broadcast Muslim calls to prayer, about 1 a.m. Wednesday as they played what appeared to be the audio from a pornographic film at a loud volume.


The 53-second video, which featured the sound of amused witnesses laughing, quickly went viral on YouTube.

Kastamonu Mayor Tahsin Babas promised an investigation in a Facebook post.

"The unmoral provocation that had been conducted by intercepting the announcement system of our municipality and heard in certain spots in our Kuzeykent neighborhood has no relation with our institution. The necessary legal processes will be launched as soon as possible for those who are responsible for this unmoral act and we apologize to our precious fellow townsmen for this situation," Babas wrote.

Social media users theorized workers at a city building were watching the adult film and forgot to shut off the speakers, security officials said they suspect the municipal frequency used to broadcast through the speakers was intentionally intercepted by pranksters.

"We think that they intercepted the municipality frequency because it occurred in only one region. It would have occurred everywhere if it was the municipality's central announcement system. One can broadcast what he or she wants after spotting the frequency wave," investigators told Turkey's Dogan News Agency.
