JACKSON (AP) — Police say the driver of a Greyhound bus that flipped Wednesday night injuring nearly two dozen passengers was drunk.

The driver has been charged with driving under the influence after the bus overturned on an interstate highway in Jackson, Mississippi and caused injuries that sent nearly 22 passengers to hospitals.

Jackson Police Sgt. Roderick Holmes said in a news release the wreck happened about 8 p.m. Wednesday on an entry ramp on Interstate-55 during heavy rains.

Holmes says the bus driver, 31-year-old Erika Nixon, is charged with misdemeanor DUI.

First responders said all the passengers were safely removed from the bus. Twenty-two of them were sent to hospitals in the area. No serious injuries have been reported.

It was not immediately known whether Nixon has an attorney.
