The Pittsburgh Bureau of Police is warning the public about a recent string of catalytic converter thefts from vehicles. 

Over the past three weeks, four catalytic converters have been stolen from the undercarriages of vehicles in the Friendship, Bloomfield and Garfield neighborhoods. 

Multiple similar thefts or attempted thefts have been reported throughout the city this year. The majority of the incidents are believed to have occurred in the overnight hours.  

Vehicle owners report hearing a very loud sound after starting their engines before discovering their catalytic converters missing.

Police are appealing to the public to be aware of any individuals who they don’t normally see in their neighborhoods, as well as any vans or trucks that are out of the ordinary, as thieves often work in tandem. They also encourage neighbors to share information and, when possible, train any home security cameras toward parked vehicles if there is concern.  

As always, any suspicious activity should be reported to 9-1-1 immediately.
