Eleven people were hospitalized after being stabbed at a homeless services provider in downtown Salem, Oregon, on Sunday night.

Axar.az reports, citing NBC news, a suspect was in custody after the violence at 7:15 p.m. at Union Gospel Mission, Salem police spokeswoman Angela Hedrick said.

The injured were taken to Salem Hospital, Hedrick said by email. Details about their injuries were unavailable and Salem Health, Salem Hospital’s corporate parent, did not immediately respond to a request for comment Sunday night.

The suspect was described only as a man, and no identity was available.

Executive Director Craig Smith said in a late-night phone interview Sunday that the attacker was new to the mission, having spent Saturday night there, and was about to check in for a second night when he got into a fight.

“Something ... set him off, and he evidently had a knife in his bag,” Smith said.

The altercation took place right before the man would have handed over his belongings to staff, and at least one staffer, who was working the mission's check-in desk, was injured in the attack, Smith said.
