BREMERTON, Wash. -- Bremerton police said four banks were vandalized early Thursday, with each incident involving windows broken with pieces of concrete that had notes taped to them, reported KIRO 7 Eyewitness News.

The banks involved were a US Bank at 2020 Sixth St., a Key Bank at 3750 Wheaton Way, a Bank of America at 1000 Sixth St. and a Kitsap Bank at 3425 Wheaton Way.

According to police, the vandals did not go in any of the banks.

“No entry was gained and nothing was taken, so it appears this was the delivery of some kind of message by the perpetrators,” Andy Oakley with Bremerton police said.

Police said the content of the notes were all the same and read as follows:

“Directions: Attach to brick and throw through window”

“Here is your brick back."

"Recognize it? You should.”

“It is part of the wall that you, as one of the elite upper class, have helped to build between the minority ruling class, and the majority working class throughout history. By flaunting your decadence, you have made yourself a target.”

“Get used to it!”

“Social youth chaos-f___ s___ up!”

The pieces of concrete and notes will be forensically examined, and bank surveillance tapes will be reviewed, police said.

“We’ve also contacted the FBI because of the apparent political nature of the note to see if we can get some information there. We have not seen this activity prior in the city,” Oakley said.

Anyone with information about the case is asked to call Detective Robert Davis at 360-473-5361 or Crimestoppers at 1-800-CRIME-13.
