Catalytic converter thefts return to Pittsfield Township

The thefts occurred in the 4700 and 4800 block of Washtenaw Avenue and 2100 block of Arbor Circle West.

Police say all four thefts were reported Aug. 6. Converters were stolen off a 1999 Pontiac Grand Am, two different 2001 Chevy Cavaliers and a 2002 Chevy Cavalier.

Officials say replacing a catalytic converter can cost about $1,000. In addition, vehicles are sometimes damaged when the catalytic converter is taken.

The catalytic converter is used to convert harmful pollutants into less harmful emissions before they leave the exhaust system. It's located in the car's exhaust system, and precious metals such as platinum, palladium, rhodium or gold are used as the catalyst. Police say thieves sell the converters to metal recyclers, who then extract the metal and resell it.

In February, numerous catalytic converters were stolen in Ann Arbor, Pittsfield Township, Ypsilanti Township and on the University of Michigan campus.
