Eight people were stabbed and injured and the suspect was killed by an off-duty officer at Crossroads Center, a mall in St. Cloud, MN, on Saturday about 8:15 p.m.
St. Cloud Police Chief Blair Anderson said the victims were stabbed by a man dressed in a private security uniform.
An off-duty police officer from another jurisdiction shot and killed the attacker, Anderson said. Anderson did not say where that officer serves during the news conference that started after midnight.
According to St. Cloud Mayor Dave Kleis, the shooting happened inside Macy's.
Anderson said the attacker, who was armed with a knife, reportedly made references to Allah during the attack and asked at least one person whether they were Muslim. But Anderson pointedly declined to call the attacks an act of terrorism, saying the motive isn't yet known, the St. Cloud Times reports.
