A couple, presumably in love, posted a short 13 second video clip of the man professing his love by etching into a rock face on the road up Doi Inthanon.
The video went viral and received widespread condemnation.
Authorities say that they have now found the couple and have told them that they broke the law by desecrating a rock face in a national park. The pair have been warned and authorities are cleaning up the rock face, removing the etching.
