Cambridge Police Warn Residents About Increase in Catalytic Converter Thefts

The Cambridge Police are warning residents about a recent increase in catalytic converter thefts in Cambridge. Catalytic converters, which are part of a vehicle’s exhaust system, are most sought out by thieves because they contain precious metals and can be sold for scrap. In addition to Cambridge, thefts of catalytic converters are also reportedly rising across the country.

After a series
of thefts were reported by residents primarily in the Cambridgeport neighborhood between January 16-17, another surge of thefts has occurred in the Wellington-Harrington and East Cambridge neighborhoods over the last two weeks. All reported catalytic converter thefts that have taken place this year in Cambridge have involved 2004-2009 Toyota Prius’.   

Using a data driven-approach, officers have increased their patrols in the locations and during the times in which a higher volume of these thefts have been reported. The Cambridge Police recommend the following tips to prevent catalytic converter theft:

  • Park in well-lit areas.
  • Park close to building entrances or the nearest road in public parking lots. This leaves your vehicle in a location where many people can see it.
  • If you have a personal garage, keep your vehicle parked inside with the door shut.
  • Add video surveillance to the area where you regularly park your vehicle.
  • Install a catalytic converter-specific security device, or have the catalytic converter welded to the vehicle’s frame. You can also engrave your vehicle’s VIN number on the catalytic converter.
  • Adjust the security system on your vehicle, if already installed, to activate from vibrations, such as those produced by a saw.
  • Remember to call the police and report where your car was parked when your catalytic converter was stolen. Provide as many identifying details that you can.


Anyone with any information related to these thefts is asked to call the Cambridge Police at 617-349-3300. Those who wish to provide information anonymously may dial the Cambridge Police Anonymous Crime Tip Hotline at 617-349-3359 and leave a message.  Anonymous tips may also be sent via the Cambridge Police MyPD mobile app or via text message to 847411.
