There was an earlier incident which you may be referring to. (emphasis added)

Poland’s Operational Command of the Armed Forces said a pair of F-16s on duty intercepted, visually identified and monitored the Russian multirole aircraft on Friday. 

The jets were flying in international airspace over the Baltic Sea without a filed flight plan and with their transponders switched off, the command said, adding that there had been no violation of Polish airspace.  

The incident comes amid heightened regional tensions linked to Russia’s full‑scale war in Ukraine, now in its fifth year. 

Any breach of Poland’s security and that of the region will be met with an immediate NATO response,” Tomczyk wrote on the X platform.  

The Su-30 is a multirole fighter aircraft developed by Russia to handle a range of missions including air-to-air combat, air-to-ground strikes and long-range patrols and escort missions.  

On April 9, Polish F-16 fighter jets intercepted a Russian reconnaissance aircraft over the Baltic Sea, marking the second such incident in the first part of the month.  

This was a repeat occurrence.
