Catalytic converters were stolen from half a dozen vehicles in a train station parking lot in East Chicago Monday, police said.
The thefts took place a parking lot at the South Shore commuter rail station around 11:20 a.m., according to Northern Indiana Commuter Rail District Transit Police.
Transit police said security camera footage shows the catalytic converters, which will likely be sold for scrap metal, were removed within minutes as the thieves used battery-operated, high-powered reciprocating saws.
Several vehicles were towed following the thefts because exhaust systems were left hanging from cars, according to authorities.
All six vehicles impacted by the thefts, which will cost victims more than $1,000 in repairs, were Chevrolet Cavaliers, officials said.
Transit police are asking anyone with information about the crimes to call NICTD Transit Police at (219) 398-6000.
