A fraud case against Brazilian superstar Neymar and his father in relation to the player's 2013 transfer to Barcelona was re-opened on Friday following a successful appeal by Spanish prosecutors, a court filing showed.

In July a judge ruled that irregularities in the high-profile transfer were detected, but said it was an issue for a civil court, not a criminal court to settle.

However, prosecutors successfully argued the player and his father were aware of potentially fraudulent dealings between Barcelona and his former club Santos to the detriment of DIS, a Brazilian investment company who owned 40 percent of the player's sporting rights at the time of the transfer.
