ST. CLOUD, Minn. -

An off-duty officer shot and killed the suspect who police say attacked nine people at the Crossroads Mall in St. Cloud.

The man's father identified him Dahir Adan.

The FBI is investigating this as a potential act of terrorism.

Police responded to the attack just after 8pm Saturday, and say none of the victims have life–threatening injuries.

"Everyone was screaming and everything was just starting to get really chaotic," says Ashley Bayne, who was inside the mall when the attack happened.

"I was just starting to realize and put the pieces together that maybe I should start running too, people were screaming that there was a guy stabbing people in the mall, and I ended up being like, I have to go I have to go," Bayne says.

Ashley fled the mall and drove away before police put it on lockdown.

Officers recorded ID's before letting anyone out.

Investigators say the suspect was not an employee of the mall.

"There's no imminent threat. The suspect did have on a private security uniform, and again, we're in the process of figuring out if the suspect was actually an employee of a private security firm," St. Cloud Police Chief Blair Anderson says.

The off duty officer who shot the suspect is Jason Falconer of Avon, Minnesota.

St. Cloud Mayor Dave Kleis watched the mall's surveillance video, and says Officer Falconer saved lives.

"You saw him lunge at the police officer. The officer then fired a few rounds, you see him fall, then you see him get back up," Mayor Kleis says.

This happened three times; the suspect repeatedly getting back up and lunging at Falconer.

"He protected others from being injured, and potentially loss of life. Clearly a hero," Mayor Kleis says.

Authorities say the suspect made references to Allah during the attack.

The Islamic State group claims the attack was their own, but it is unclear if they even knew of the attack before it happened.

Central Minnesota Somali leaders condemned the attack.

"We do not at this point in time know whether the subject was in contact with, had connections with, was inspired by a foreign terrorist organization, that's what the investigation is attempting to ascertain," FBI Special Agent Richard T. Thornton says.

Only three of the nine people injured are still being treated at area hospitals.

The mall is set to reopen tomorrow.
