Three Ajax youth team players have been suspended amid an investigation into an alleged beating of a female officer.
Dutch police questioned forwards Zakaria El Azzouzi, 18, Samet Bulut, 19, and midfielder Ashraf El Mahdioui, 18, in connection with the incident.
It is alleged that a plain clothes policewoman sounded her car horn at another vehicle on Thursday night and there was a confrontation.
Ajax said it takes the allegations "very seriously" and is investigating.
In a statement, the club added that it is "doing everything it can to find out what happened.
"Until then the players will not take part in any football-related activities."
