According to the Wauwatosa Police Department, authorities received a call about an accident involving a yellow Public Works vehicle shortly after Noon.

Two more people were transported to a nearby hospital for emergency evaluation and care. Their current condition has not been made public. One other person was injured, but not hospitalized as a result of the incident.
