Four people were arrested this week after police uncovered one of the largest suspected stashes of stolen catalytic converters in Los Angeles County. Investigators say officers found roughly 1,800 suspected converters at a Norwalk property, parts they estimate are worth more than $500,000. The arrests capped a months-long probe led by Baldwin Park detectives that began in July 2025.
Massive Norwalk Stash
According to KTLA, officers seized about 1,800 suspected stolen catalytic converters at a Norwalk storage site and impounded four vehicles as evidence. Photos released by investigators show three men and one woman being handcuffed and taken into custody at the scene.
Multi-Agency Crackdown
Police said the lengthy probe involved detectives from Baldwin Park coordinating with allied agencies across the region. "The investigation remains active and additional arrests are anticipated," police told KTLA, adding that authorities identified a South Los Angeles site used to buy stolen converters during the operation.
Why Converters Are Targeted
Catalytic converters contain small amounts of precious metals that make them valuable on the black market, driving a years-long surge in thefts, according to the National Insurance Crime Bureau. Local officials have pushed for stricter rules for scrap dealers and stepped-up enforcement, and a recent countywide crackdown roundup compiles those efforts.
What’s Next
Investigators have not released the suspects' identities, and it is unclear whether prosecutors have filed formal charges. Detectives say they are continuing to process evidence and follow leads. Police investigators said they will try to match recovered parts to victims and buyers as the probe moves forward.
How To Help
Anyone with information is asked to contact the Baldwin Park Police Department at (626) 960-1955 or submit an anonymous tip to Los Angeles Regional Crime Stoppers at 1-800-222-TIPS or online. Officials also urged vehicle owners to consider VIN etching and to attend community etching events that help make stolen converters harder to fence.
