GLENDALE, Wis. (CBS 58) -- A 21-year-old Glendale woman is being charged with a hit and run causing great bodily harm after a motorcyclist was seriously injured in Bayside in August, according to a criminal complaint.

Dua Rizvi is accused of crashing into Richard Schwartz near W. Brown Deer and N. Port Washington roads on Sunday, Aug. 23, then leaving the scene, the complaint states.

Witnesses told police a silver Toyota struck Schwartz's motorcycle and drove off, then followed the car as it fled onto the freeway.

Schwartz suffered spinal fractures, a brain bleed and other serious injuries, according to the complaint.

Rizvi later met with officers and told them she believed the motorcyclist had hit a curb, maintaining she didn't know she'd struck anyone, the complaint notes. Investigators say surveillance video shows the motorcyclist thrown in front of her windshield.

Rizvi has not been convicted. Her initial court appearance is scheduled for Wednesday, Sept. 23.
