If the ship was correctly identified here:

Then it was accepted into service back in 1988 and was indeed built in Poland. Atleast one of the ships in that class did receive electronics refit in 2008 but not the specific ship identified. In my opinion they are just blowing the regular recon patrol out of proportion. I mean for all we know it could have been regular patrol related to new-START treaty.
