Sagan Tosu manager Kim Myung Hwi has been accused of continuing to subject players and others to violence, abusive language and abuse of power, a source close to the matter said Tuesday.

The anonymous accusation was made to the Japan Football Associations' consultation desk for stamping out violence, with the J-League set to discuss whether to launch its own investigation into the matter.

The 40-year-old Kim was suspended from managing by his club in June for three matches after he swept a player's foot during practice and floored him, which was deemed to exceed the scope of his duties.

Sagan set up a third-party panel to investigate the matter but decided no further punishment was necessary, allowing Kim to return to manage the team on Aug. 14.

The source said the accusation indicated that Kim's abuse of power had been taking place also before the incident that resulted in his suspension, adding the club's investigation was insufficient and that scrutiny from an objective standpoint is needed.

A Sagan spokesperson said the club had not heard from the league and would respond after understanding the situation based on a confirmation of the facts.
