Alwaght- At least five people have been killed more than 40 injured in the city of Waukesha, Wisconsin after a speeding SUV plowed through a Christmas parade on Sunday.
Waukesha Police Chief Dan Thompson said a person of interest was in custody and a vehicle had been recovered after the incident in the town, about 20 miles (32 km) west of Milwaukee.
"At this time, we can confirm that 5 people are deceased and over 40 are injured," the Waukesha Police Department said on its Facebook page. "However, these numbers may change as we collect additional information. Many people have self-transported to area hospitals."
It was not known whether the incident was related to terrorism, but there was no further danger and an earlier shelter-in-place order in the town of around 72,000 had been lifted, Thompson earlier told reporters.
A video posted online showed a red sport utility vehicle plowing at speed through the parade, appearing to run over more than a dozen people before crowds ran from sidewalks to offer assistance.
Thompson said an officer fired shots at the vehicle and no bystanders were injured. Police did not believe shots had been fired from the vehicle, he added, contrary to earlier reports. Video on social media appeared to show police firing on the vehicle as it crashed through street barriers.
