I read somewhere that the Brazilian midfielder Mancini has been sent to prison – what was he charged with? 

Daniel Poer:
Yes, on November 28th, 2011, Mancini was sentenced to two years and eight months in prison, after being found guilty of sexual assault.

The incident allegedly took place during a party hosted by Ronaldinho in Milan in 2010, where Mancini is reported to have raped a Brazilian girl.
Mancini was sentenced in Milan.
