Parents and children watched in horror as two bondage-clad porn stars paraded through a popular Spanish hotspot and simulated lesbian sex.
Police are investigating the illegal porn shoot in Seville featuring two women wearing nothing but high heels and bondage attire.
The women posed for a camera crew in a park and in front of governmental building, Palace of San Telmo.
They also shocked locals and tourists during their broad daylight jaunt by hopping onto a horse-drawn carriage with no clothes on for another X-rated display.
The shoot on Saturday moved from place to place so swiftly officers were unable to catch them red-handed after being alerted by astonished onlookers.
Many of the shock scenes were filmed by a single cameraman, acting in conjunction with a second person thought to be the director.
One mum said: “I couldn’t believe what I was seeing. It was really shocking.”
Shop owner Manuel Gonzalez said: “Two naked women got out of a horse-drawn carriage and began to pose for a cameraman.
“There was a man with the video-camera and another with tripods, lens and clothes for the girls.
“Some people protested but most crowded round and began to record them on their mobiles. They left before the police arrived.”
Police are understood to be focusing on the fact kids witnessed the shoot, which would be considered criminal, rather than the simple fact the women protagonists were naked which is not a crime.
Town hall chiefs working with the help of local police were today trying to identify the camera crew and two women.
A town hall source said: “The Spanish Penal Code states that a person who commits or coerces another person into committing acts of obscene exhibition in front of minors, can receive prison sentences of up to a year as well as a fine.”
The local council is also studying the possibility of asking state prosecutors to launch a separate investigation.
Police suspect a company specialising in X-rated cinema is behind the shoot.
Madrid and Barcelona have been picked for similar unauthorised shoots in the past.
