A female Northwestern University employee in her 70s was injured Tuesday evening after being struck by a vehicle on Sheridan Road.

Police responded to the call just after 7 p.m. when the woman was hit by a tan Mercedes heading south between Foster and Emerson Streets, Evanston Police Chief Richard Eddington said.

The woman was taken to Evanston Hospital, 2650 Ridge Ave., but the extent of her injuries were unknown he said.

Eddington said the driver of the vehicle stopped immediately and was cooperating with police. Witnesses were taken to the station for further questioning.

“At this point, there is no indication that improper driving was a factor,” Eddington said.

Police blocked off both north and southbound lanes of Sheridan Road while the station’s accident investigation team inspected the scene. The woman’s bag and umbrella were left on the street and were being used by officers to determine what may have happened, Eddington said.

The investigation was ongoing Tuesday night while Northwestern University Police contacted the woman’s family.
