Football's global governing body, FIFA, announced on Thursday that its disciplinary committee had opened proceedings against Spanish Football Federation (RFEF) President Luis Rubiales.
The move comes amid outrage over Rubiales forcibly kissing Spanish player Jenni Hermoso on the lips following last Sunday's World Cup final.
In a statement, FIFA said the incident "may constitute violations of article 13, paragraphs 1 and 2 of the FIFA disciplinary code."
Article 13 deals with the "offensive behavior" of players and officials, particularly in terms of "violating the basic rules of decent conduct" and "behaving in a way that brings the sport into disrepute."
