Bogus GNR police in Portugal

Told from good source about good mates of coppers nicking their cars and uniforms,while the real copper was on a bender,and nicking foreign truckers in Portugal,in the 80s and 90s.False weigh bridges rigged to higher load weights,running on a fictious public holiday or road or junction where no triucks are allowed.Pay cash up front or they say company pays the fine,which would be 4 or 5 times more than the “coffee money” bribe.Overheight trailers with JCB`s was a favourite trick.And real GNR coppers,that lived beyond their “normal” salary,and neighbours got suspicous,as they took expensive holidays/new cars/swimming pools,and gold jewellry.When in Portugal,read about GNR getting jailed for alledged activity.Wasnt there a “false weigh bridge” on the forest road,south of Bordeaux,think they got nicked for fraud.?
