San Francisco police are investigating three possible sexual assaults which occurred at the Outside Lands music festival over the weekend, according to reports.
Three different women claim to have been assaulted by three different men -- at three different times and locations over the three-day music festival, according to SF Weekly.
Hence, the attacks are not related, police believe. The women may have been drugged before they were attacked, the newspaper reported.
Results of forensic tests are pending, the newspaper reported. In the meantime, police are asking for the public's help.
Any witnesses to the alleged attackes are asked to "contact the San Francisco Police Department's anonymous tip line at 575-4444, or Text-A-Tip to TIP411," the newspaper reported.
