Dodgy workmen

 On UK TV you often hear about dodgy workmen ripping off vulnerable people, this is how the law works in France;

Providing false information in order to dishonestly obtain monies,securities, property or a service or to dishonestly obtain consent to an act or the discharge of an obligation, and which involves prejudice to the owner, is fraud which is punishable by five years imprisonment and a 375,000€ fine.
The penalty is increased to seven years imprisonment and a 750,000€ fine if the fraud is against a person with a particular vulnerability such as age, illness, infirmity, physical or mental disability or pregnancy which is apparent or known to the perpetrator. The penalty is increased to ten years imprisonment and a 1 million Euro fine when the fraud is committed by an organised gang.
