A 15-year-old boy has been arrested in connection with a shooting at a Milwaukee shopping mall that injured eight people, authorities said.

Wauwatosa Police Chief Barry Weber said the shooting happened during a dispute on Friday afternoon between two groups. He said four “innocent bystanders” suffered what were believed to be non-life threatening injuries.
