Sort of a hard question to answer without knowing what your scanning but the easy answer might be what's called a "header" or "birdie" this is where a freq is used by a near by electronic device. Could be your computer, could even be the scanner itself.
Birdies are frequencies your scanner uses when it operates. The most common birdies to watch for are listed below.
31.05 MHz 124.20 MHz
41.40 MHz 134.55 MHz
51.75 MHz 144.90 MHz
113.85 MHz 155.25 MHz
If you lock out that freq you should solve that problem or move your radio away from electronic stuff.
Now if it's locking on a known active freq it could be something totally different.
If you're trying to follow trunked radio traffic which most police and fire use now you need a trunk tracker scanner to follow the action.
Again the short answer is trunk radio is computer controlled and jumps around to all sorts of freq so you will need a trunk tracker radio to follow, you can listen with a normal scanner but you will only hear parts of conversations.
Officers are not normally assigned certain channels they all work off one main dispatch channel then sometimes go to "tac" channels or "car to car" channels.
Undercover and detectives will often have their own channels to work on but officers are not assigned certain channels. In fact they don't really use channels at all anymore they have what's called "Talk Groups"
Scanners are pretty complicated these days with Trunked and Digital Radios it can be a pain to follow along.
