Wauwatosa police have arrested a 15-year-old Milwaukee boy who is accused of opening fire at Mayfair Mall Friday afternoon.
Eight people were wounded, but all are expected to survive.
Police Chief Barry Weber says the suspect was taken into custody Saturday night and the weapon used in the shooting was recovered.
The mall was closed after the shooting Friday and remained closed Saturday, however, some stores reopened Sunday.
Investigators say the shots were fired as the result of an altercation between two groups of people inside the mall.
Four of the wounded victims were innocent bystanders.
