(Bloomington, MN)  —  Police in Bloomington say shots fired at the Mall of America were part of an ‘isolated incident.’  A lockdown was lifted last night about two hours after a dispute between two groups of people outside a Nike store escalated to gunfire.  Police believe there was only one shooter and that there were no indications that anyone was hurt.  Authorities were still looking for the shooter hours later, who had left the scene right after the incident.
