As of October, the NYPD says 7,000 catalytic converter thefts have been reported in New York City, which is twice more compared to last year.

Catalytic converters change and reduce the amount of pollution that comes out from an engine’s emission. They are made up of rare metals like platinum that can be worth over $1,000.

The city council wants to make it easier to keep track of where these parts are coming from. So, they are voting on a bill that would require buyers to have proof from the seller about what car the catalytic converter came from and that the seller got the part legally.

On Friday from noon to 4 p.m., the Bronx district attorney's office and the NYPD will hold an event at Orchard Beach where community members can get the catalytic converters in their cars marked and labeled so that if yours is stolen, it'll be easier to track.
