ST. CLOUD (AP) - The father of the man who stabbed nine people at a St. Cloud mall has identified him as a 22-year-old college student.

Ahmed Adan says police told him Saturday night that his son, Dahir A. Adan, died at Crossroads Center mall in St. Cloud.

He says police didn't mention the attack on the mall, but they seized photos and other materials from the family's apartment.

Authorities haven't publicly identified the attacker. They say the attacker stabbed nine people Saturday night before an off-duty police officer shot and killed him. None of the victims suffered life-threatening injuries.

Ahmed Adan, who is Somali, says his son came to the U.S. 15 years ago and was was a student at St. Cloud Technical and Community College. He says he had "no suspicion" that his son might have been involved in terrorist activity.

The Islamic State group has claimed responsibility for the attack.

Meanwhile, St. Cloud Technical and Community College says Adan was never a student there, as has been reported. St. Cloud University confirms he attended school there, but has not been enrolled since spring 2016.
