Police in the US have arrested the owner of a company called Whoops Towing as he tried to haul off an undercover vehicle.
Oregon State Police say they had received reports that a towing business operating without the required certificate was posting its own impoundment warning signs in car parks and using a spotter to generate tows.
Police say they parked the unmarked vehicle as part of the investigation, and 35-year-old Michael Alan Selmer of Falls City showed up in the tow truck.
They arrested him on charges of failure to register as a sex offender and violating parole terms.
The towing investigation is being reviewed by Marion County prosecutors.
A call to Whoops Towing went unanswered, and it is unclear if Selmer has a lawyer.
