The belated arrival of the Swedish summer sun on Wednesday had brought the crowds out in force to a popular swimming jetty on Lake Vänern.
Apparently overcome by the moment, one couple moved on from innocent kissing and cuddling to full intercourse in plain view of groups of families with children.
The families couldn't help but witness the events unfolding before their eyes, and one of the parents felt compelled to act and called the police.
According to the TT news agency, the parent said that the call had to be made in order to protect the children from the sight of the copulating couple.
A police unit was dispatched to the location and when they arrived the couple had completed their exertions.
According to the police the lovers were somewhat sheepish and expressed some understanding for the complaints from the innocent bystanders.
The police at first considered whether the couple could face charges of sexual molestation, with their audience identified as the victims in the case, but the police have decided to close the investigation.
Sexual molestation (sexuellt ofredande) is a crime under Swedish law and can for example apply to flashing or groping, as a well sex chat with minors.
