Bordeaux - French police are investigating a claim of rape made by a young woman against players from Top 14 rugby club Grenoble, prosecutors told AFP on Monday.

"The public prosecutor's office was informed yesterday (Sunday) of a complaint filed by a young woman denouncing acts of rape, an investigation began immediately," the prosecutor said.

"But no one has been taken into police custody so far in this case," the same source added.

According to radio station France Bleu Gironde, the alleged victim told police she met several Grenoble players in a nightclub on Saturday night after the club's Top 14 defeat in Bordeaux.

She claimed that some of them drugged her and then "forced her to go to a hotel where she was raped," the radio station reported.

The investigation will have to establish the course of events, a source close to the case said.

"The club will not comment on the investigation, we'll let the police do their job," a Grenoble spokesman told AFP.
