Having lived and worked in Brasil for five years a few years back and having now visited Europe in general and "cleared" customs in Frankfurt many times, IMHO, the principal threat is upon your friend's return to Brasil. (Please be aware that I only cleared customs in Rio and San Paulo as part of my travels to Miami about every two months during this period.Thus I can not comment on entry issues in other gateways into Brasil.)
Good luck
