Hearing something?

Starting around 3:15 this afternoon, the sound of helicopters could be heard in the Green Lake neighborhood.  As of 3:55, the noise is still present.

While we can’t pinpoint the cause with absolute certainty, it seems likely that the helicopters are connected to a large police operation currently going down in the U-District:

SWAT teams have surrounded a home in the 5200 block of 12th ave NE in University District looking for a bank robbery suspect.

SWAT has called for the armored Bearcat and units from other precincts are assisting at the scene.

According to the scanner, a King5 helicopter is hovering overhead and making operations “difficult.”
