West Yorkshire Police said vehicles stolen from Leeds, Bradford, Kirklees, Calderdale and Wakefield had been traced to Lancashire.
Chief Supt Pat Casserly of West Yorkshire Police Protective Services Operations said: “This planned proactive policing operation has been as a direct result of extensive dedicated work of West Yorkshire Officers across the border with colleagues in Lancashire.
“The scale and organisation of the sites have been quite remarkable as this appears to be a well organised, systematic and efficient process to deconstruct vehicles, categorise them and move them on for sale.
“Whilst collectively these incidents result in high value crime, we must remember that each theft has very human consequences. These types of vehicles are often owned and utilised by small businesses and for some, the theft of a vehicle can result in the loss of contracts and future work.”
