The GVSU Police Department is investigating a string of car parts thefts that all occurred on the Allendale campus.

Since Monday, Oct. 30, there have been eight separate reports of catalytic converters being stolen from cars.

The catalytic converter is a car part that sits underneath the car and used to convert chemical pollutants from the engine into exhaust fumes. They are typically made up of precious metals such as platinum, palladium and rhodium -- depending on what model the car is.

According to officials, many of the cars robbed are older models and it's believed they are sold for scrap metal. GVPD believes the converters are being sawed off using a reciprocating saw, and due to the location, the thieves are using car jacks to remove it.

The first report of a theft was on Oct. 30, but it is possible that all eight thefts happened that same night GVPD says.

The university is urging all students to report any suspicious activity to GVPD at 616-331-3255 or the Ottawa County Silent Observer hotline at 877-88-SILENT (745386).
