Jerome Valcke faces criminal proceedings after the Office of the Attorney General (OAG) of Switzerland announced it was conducting an investigation into the former FIFA official.
The 55-year-old served as secretary general of world football's governing body between 2007 and 2015, but was dismissed from the role in January and hit with a 12-year ban last month after an investigation by FIFA's Ethics Committee found him guilty of numerous acts of misconduct.
And the OAG, which has also opened proceedings against former FIFA president Sepp Blatter "on suspicion of criminal mismanagement", has now confirmed it does not end there for Valcke.
"As part of the ongoing series of cases relating to FIFA, the OAG is conducting criminal proceedings against the former FIFA Secretary General Jerome Valcke on suspicion of various acts of criminal mismanagement (Art. 158 Swiss Criminal Code) and other offences," the organisation said in a statement.
"The OAG opened the proceedings in response to two criminal complaints in which allegations were made against Jerome Valcke in connection with the matters investigated by the FIFA Ethics Committee.
"The OAG began investigations in this connection and conducted searches and interviews on 17.03.2016; no arrest has been made. The presumption of innocence applies."
