Investigators from the federal public prosecutor’s office visited the headquarters of the Belgian football union in Laeken on Wednesday, according to the federation’s spokesman.
Around 30 investigators also went to the R.S.C Anderlecht’s administrative and training centre in Neerpede.
The visits are part of an investigation into laundering and organised crime, targeting mainly player’s agents.
The investigators took away documents related to transfers, the federation spokesman disclosed.
A search was also conducted in Schaerbeek.
