Officers say it began when they responded to a burglary call on Tuesday afternoon at a building at 24th and Madison streets in the city.
When they went inside, the officers said they found about 100 plants growing inside. Police say each plant was about five feet tall with 2-inch diameter stalks.
There was no immediate word on if anyone was inside.
The view from Chopper 6 HD showed officers removing plants, growing lights and other materials.
