Police say Carter entered the taxi with 20-year-old Cory Jackson and a third passenger who has not yet been identified at 4.24 am on January 28.
In addition to the assault Carter and Jackson allegedly took $32 from the driver 's wallet.
Detective Lt. Robert Ring of Findlay police department said of the sexual assault: "We don't know why she did it. Maybe it was a distraction because they took money from him." After the passengers fled the scene the taxi driver reported the incident to police.
An indictment accuses Carter of “having purposely compelled” the victim to engage in sexual conduct “by force or threat of force.”
Carter is being held at the Hancock County jail, with bail set at $60,000.
