Catalytic converters are car pieces that help reduce overall vehicle emissions. It converts dangerous pollutants into less dangerous emissions before leaving the car exhaust system. According to an article in the Denver Post, catalytic converters contain precious metals which can be sold as scrap metal. Some converters can bring in profits of $30 and others over $100.

Over the four-month theft spree, 46 incidents were reported to the Fort Collins, Colorado State and Loveland Police departments. There are also approximately 60 other known instances of catalytic converter theft in other towns across the Front Range.

The Fort Collins Police Department is leading the investigation and is collaborating with various other police departments in Loveland, Broomfield, Colorado Springs, Aurora, Denver and Greenwood Village. The Colorado State Patrol has also provided support in the investigation.

Fort Collins residents who have recently been victims of catalytic converter theft and have not reported to authorities are encouraged to contact Officer Chris Renn at 970-416-2385.
