Sioux Falls has seen a recent increase in the theft of catalytic converter. Thieves steal these emission control devices for the value of the precious metals they contain. The stolen converters are then quickly "converted" into cash by either selling them online or to a salvage yard.

Sioux Falls police say that there have been 40 to 50 reported converter thefts in the last few months in the city. The Turner County Sheriff's Office reported converter thefts in Marion, Parker, and Rural Viborg.

Sioux Falls Police announced they have arrested suspects who they say were caught stealing a number of catalytic converters from vehicles found inside a Sioux Falls salvage yard.
