Broken Arrow Police say the vandals shot out the window of a credit union; it's the second time the credit union has been hit in the past eight days.


The vandalism is not only a nuisance, its costing businesses thousands of dollars to replace windows. Credit Union assistant manager Vikki Seggebruch: "We replaced the door the first time and of course, had to have it boarded up until it was repaired. This time, it only broke the front pane, it's a double pane."


Broken Arrow Police officers are investigating 17 of these incidents in the past few weeks. A cluster has emerged around Kenosha and Aspen as well as along Elm between Kenosha and Houston.


The shootings generally happen after 9 PM and before 4 AM.
