A van plowed into a crowd gathered for a Labor Day parade Monday in Illinois, injuring 11 people, according to reports. A 2-year-old suffered a fractured skull in the incident, which reportedly delayed the parade by over an hour.

Officer Tom Kirby of Westville Police Department reportedly said late Monday that the driver, a 61-year-old woman, was taken in custody. She was not seriously injured. The vehicle, traveling eastbound on Main Street, struck several people on the west side of Route 1 and then struck spectators on the east side.

"She never stopped," a witness told CNN affiliate WICS. "It's just too scary to see anything happen like that."

Westville Police Chief David Booe said Monday that authorities are yet to determine whether the driver had any medical issues. The vehicle involved in the incident is reportedly being checked for possible mechanical glitches.

“At this time it does not appear that any of the injuries are life threatening, although this can change,” Westville Police Department said in a statement on its Facebook page.

The Vermilion County Sheriff's Department is reportedly assisting with the investigation.
