Boise, ID – Police arrested a man who stabbed nine people, including six children, at a refugee apartment complex in Boise on Saturday night.

“We haven’t had anything involving this amount of victims in a single attack in Boise in the history of the department,” Boise Police Chief William Bones said as he described the scene during a press conference, NPR reported.

The chief said the incident began at about 8:46 p.m. on June 30, when police received a call for man with a knife.

“The report was the man was attacking victims here at the Wylie Street Apartments,” Chief Bones said.

Officers responded to the scene in under four minutes, but the suspect had already fled on foot, he said.

The suspect was located “almost immediately,” according to the chief, and officers took 30-year-old Timmy Kinner into custody at gunpoint.

Officers searched the apartment complex and found nine victims in apartments and in the parking lot, Chief Bones said.

Police said six of the victims were children, and four sustained “life-threatening injuries,” according to KIDK.

All of the victims were transported to the hospital for emergency care. No other details on the victims’ conditions were available.

The Idaho Statesman reported that Kinner, who is not a refugee, had been staying at the Wylie Street Apartments temporarily, and that Boise police said he had been asked to vacate the building on Friday.

Chief Bones said police did not yet know Kinner’s motive for the attack.

He was booked into the Ada County Jail on nine counts of aggravated battery and six counts of injury to a child, NPR reported.

Chief Bones did not know what kind of blade had been used in the attacks. He said police were searching for Kinner’s knife but that it had not yet been recovered at the time of the last press briefing.

The chief made a point to say that the attack was “not a symbol or a representation of our community in Boise, but it’s a single evil individual who attacked people with no provocation that we are aware of.”

Boise Mayor Dave Bieter echoed the chief’s sentiments in a tweet early Sunday morning.

The investigation is ongoing and investigators were expected to keep the scene around the Wylie Street Apartments cordoned off for at least 24 hours. Officers were heard telling residents they should go to a motel or a nearby church for shelter, NPR reported.
