Your friend may find it a little hard to have her friend court out and still remain anonymous, as her friend has already asked her to be a part of a criminal offence. If she dose not participate in the fraud ( which of course she should not do under any circumstances ) and she dobs her in and she gets court, then her friend may automatically be suspicious. At the end of the day, who needs friends like that and your friend should do her patriotic duty and report the incident to her company officials that she works for, who will find it easy to set a trap, ether with or without the federal police and catch her out. If done well her friend will be able to avoid being drawn into anything while the trap is set in place.
Hope this helps
