Police and emergency responders were descending on the downtown of a Wisconsin city after the driver of an S.U.V. plowed into a holiday parade on Sunday, leaving people injured, according to an eyewitness.
The witness, Kaylee Staral, a resident of Waukesha, just west of Milwaukee, was at the parade with her mother and stepfather. She said they were standing at the curb outside a store when a red S.U.V. came barreling down the street in the middle of the parade.
Ms. Staral, 20, who is an intern with The Milwaukee Journal Sentinel, said it was a moment of fright or flight as some spectators immediately fled the scene and others went into the street to help those who were hurt. She said many families with children sought shelter in stores.
Her mother went to help those who were injured, she said, but police officers soon came and told those who remained that there had been gunshots and directed people to seek safety inside stores.
Ms. Staral said that she had not heard gunfire but that people were injured. Information on the number and severity of the injuries was not immediately available. It was also unclear what became of the driver of the S.U.V.
“I think a lot of people are in shock right now,” Ms. Staral said. “It was scary.”
In a video posted on the city’s Facebook page, the S.U.V. is seen speeding down the parade route and a few screams can be heard from those in the crowd.
Then, seconds later, a police officer runs down the parade route, followed by a number of police vehicles as a group of children in the parade stops performing.
In a Facebook post, the Waukesha Police Department asked residents to avoid the downtown area. The police also set up a family reunification location at the Waukesha Metro Center.
The parade route ran mostly along Main Street, and was set to end on Wisconsin Avenue near Cutler Park.
This is a developing story.
