DETROIT (FOX 2) - Detroit police seized three weapons Wednesday after Shotspotter detected gunshots on the east side.
Police received an alert from the area of Pinewood and Gratiot after a building was struck by several gunshots.
When officers responded, they found shell casings outside a home, so they waited until a suspect left the home.
They were arrested and guns were recovered.
