It’s called Slapping.
Self-proclaimed artists from all over use stickers, or in particular, postal stickers to draw on. They then take that sticker and slap it on any flat surface they want.
"We are still seeing the painting graffiti a lot more. This is just something that has come onto the trend the last few years," said West Valley City Police Detective Mike Lynes.
Police say it is mostly young adults that have been using the technique to deface street signs, utility posts and the list goes on.
"We have come across, that we would actually consider, like I said the rock stars of the graffiti world that we have seen in the Salt Lake Valley here," the detective added. "These guys are not just specifically sticking to West Valley or to Kearns or Taylorsville. They are actually hitting Draper, Salt Lake City."
One teen was arrested for slapping. Police found a picture of him on instagram holding a stack of postal stickers.
"He is in a vehicle, most likely with his parents who are driving him," says Detective Lynes.
The trend is traveling by air. Mailing postal stickers across the country to the various so called artist.
"The other artist will go put that artist work up. They then take photos of it and post it on social networking sites," said Detective Lynes.
Police want to use these taggings to put graffiti artist in jail the same way they would with gang members.
On top of state laws that are broken, the post office can also hit you with a federal crime.
The stickers are government property and must be used for addresses.
