Police Radio Scanner allows you to listen in on police, fire, and EMS radio from around the world. Choose from police radios from 12 countries. For some of these countries, you can even select specific police bands. For example, if you choose the United States, you can select Washington, and then select King County.
Supported countries include Australia, Austria, Brazil, Canada, Chile, Czech Republic, Germany, Ireland, Italy, Switzerland, UK, and US. There is an additional Oldies station in case you've heard enough police drama and want to listen to some music.
