Portland Police are investigating multiple reports of vehicles with punctured tires in the area of Southeast 41st Avenue and Schiller Street.  The vandalism happened overnight Monday, on the heels of similar reports taken last week.

Victims discovering damage to vehicles are asked to file reports by calling the non-emergency number at (503) 823-3333.

There is no suspect information at this time and police are unable to say if these new incidents are at all related to a string of tire slashings in 2013.

From May to November 2013, the Portland Police Bureau's Crime Analysis Unit found more than 500 reports were filed about tire vandalism. The estimated cost of this string of vandalism to community residents was estimated to be $300,000 to $500,000.

If you suspicious activity consistent with these reports, please immediately call 911.

We offer the following suggestions and tips:

* Park your vehicle off the street and in a garage, if possible.

* Enhance your exterior lighting: leave porch lights on at night, add motion sensor lighting to the garage and add pathway or sidewalk solar lighting. Prune trees or bushes that obstruct light.

* If you have exterior video cameras, turn them toward the street to capture activity and people near vehicles parked on the street.

 The Portland Police Bureau and Crime Prevention want to help you and catch the person(s) responsible for these crimes.

Crime Stoppers is offering a cash reward of up to $1,000 for information, reported to Crime Stoppers, that leads to an arrest in this case, or any unsolved felony, and you can remain anonymous.
