A total of ten women reportedly have now told the Davis Police Department that they believe they were victims of drink spiking at local bars going back to May of this year.
Three of the women who filed the most recent reports said they were also sexually assaulted after consuming the drinks.
A Davis police official told the Sacramento Bee that in those cases the women involved had been to several bars, so it is proving difficult to identify which one might have been where the alleged incidents happened.
Davis police have responded to the complaints with additional officers on foot patrols near area bars. In May of this year the earliest reports were from three women who said they had been drinking at Wunderbar on G Street and at Bistro 33 on F Street.
Police also are recommending that people who go out drinking do so with a group of trusted friends, and that they watch their drinks closely.
American Addiction Centers' Sunrise House offers similar advice online.
