The city has about 2-thousand graffiti cases a year, and cleaning up what's left can add up to quite an expense.
Sgt. Mark Morton, with the Reno Police Department, says they received a call around 8 o'clock Saturday morning from Washoe County Library employees reporting graffiti on the outside of the building and on two county trucks.
The graffiti continued down on both sides of Center street... hitting several businesses and another county building.
"I believe it's going to be more than $5,000 in damage and for destruction of property would be a felony."
Sgt. Morton says this is not gang graffiti, instead it's taggers who usually continue their work to get as much attention for it as possible.
Police say taggers account for 98-percent of graffiti in the city.
"Most taggers like to tag, so they'll continue. They leave their monaquer, generally their name or tagging name in letters... we can also arrest them for crimes committed in the past.
Those past crimes can add up for the criminal, especially when the cost of removing their so-called "art" is handed over when a tagger is arrested.
"If it's a juvenile, the parents might have to foot the bill. If it's an adult... something like this... we as taxpayers foot the bill."
If you have any information about this crime, you can call the Reno Police department or Secret Witness at 322-4900.
