Multiple people have been shot at a shopping centre in Wauwatosa, Wisconsin.
Various routes to the Mayfair Mall have been closed by law enforcement as they seal off the area for emergency and tactical vehicles.
Wauwatosa police chief Barry Weber has said that seven adults and one teenager have been injured, but none of their injuries are life-threatening. The station interviewed several people outside the mall who said they had friends sheltering in stores inside. A motive for the shooting was not immediately known.
"We just dropped to the floor".
"We are working closely with the Wauwatosa Police Department and local officials on this investigation", she said. She said she was anxious because the store's phone wasn't being answered.
An agent who would not give his name said the mall was being "methodically" cleared.
In a statement to Fox News, Brookfield Properties, the owner of the mall, said it was "disheartened and angered that our guests and tenants were subject to this violent incident today". They declined further comment.
In February, 17-year-old Alvin Cole was fatally shot at the Mayfair Mall by Wauwatosa police.
