The France international, who missed his club's Ligue 1 clash with Ajaccio for 'personal reasons', has been accused of striking the teenager at his home on Friday night.
"Yann has acknowledged that it was an inappropriate response but provoked by the betrayal of the trust he gave to this young man," M'Vila's lawyer, Thierry Fillion, told L'Equipe.
"As it stands, no decision has been taken yet by the Rennes prosecutor on this case but the file will be forwarded to him within eight to 10 days."
The defensive midfielder was arrested on Monday and spent the night in police custody before being released at 11.00CET the following morning.
M'Vila, who has been heavily linked with a summer move away from Rennes, has so far denied all charges against him.The 21-year-old Amiens native is a regular in Laurent Blanc's Les Bleus side and is expected to join one of Europe's top clubs this summer.
