Put this clip at the arrival moment in a chase or arrest edit, after a door knocking sound builds the approach. Follow it with the dun dun dun sound for the reveal, keeping other effects out until that sequence finishes.

A short three-second police siren effect that rises and falls in a classic wailing pattern, made for project use. It feels urgent and tense, instantly suggesting flashing lights, a chase or an emergency arrival, which is why it cuts straight through a quiet scene and makes everyone pay attention.
