Peruvian prison bank run by prisoners for inmates savings

Peru's largest prison, San Pedro in Lima, has a bank for prisoners' savings - with a difference.
It is run entirely by serving inmates and a prisoner convicted of drug trafficking is the bank's manager.
The main concept is about establishing savings for their release and re-establishing trust.
