Baltimore police officers shot a man at a behavioral health clinic on the University of Maryland Medical System campus Thursday afternoon after police say he was threatening clinic staff, bystanders and officers with a knife.

Police chief spokesman T.J. Smith said officers responded for a call at 701 W. Pratt Street of an individual armed with a knife at around 1:25 p.m. Officers arrived at the facility on the fifth floor and found the man still armed and โ€œacting in an erratic wayโ€ after he โ€œhad thrown several chairsโ€ around a waiting room area. Others in the waiting room had been asking him to drop the knife, but he had refused, Smith said.

He continued to refuse the same request from officers on-scene, Smith said. After several refusals, he then โ€œcharged officers with the chair and the knife.โ€

Officers opened fire, hitting the man in the upper body and leg. An officer also deployed a Taser โ€œaround the same time that the shots were fired,โ€ Smith said. Four officers were on the scene when the shooting happened.

The 27-year-old suspect is now in critical condition at University of Maryland Shock Trauma.

Smith said police did not utilize a crisis intervention team. He wasnโ€™t sure how long the standoff lasted. โ€œIt didnโ€™t appear to be an extended negotiation by any means,โ€ he said, adding, โ€œthere were a number of opportunities, a number of moments, where officers were repeatedly asking him to put down the knife.โ€

University of Maryland Medical System spokeswoman Lisa Clough confirmed before the press conference that โ€œan incidentโ€ unfolded at 701 W. Pratt Street, which houses the University of Maryland Medical Centerโ€™s Walter P. Carter Clinics, a pair of community mental health facilities.

The Sunโ€™s Colin Campbell spoke with a witness who saw university and city police respond to the building, and saw officers โ€œcarry someone out on a gurneyโ€ who was โ€œvery bloody and in a neck brace.โ€

UMMS spokeswoman Karen Lancaster said on the scene that all staffers in the behavioral health clinic are safe, and โ€œfollowed appropriate protocol.โ€ She said she could not provide details about what led up to the man threatening others.

Smith said the Special Investigations Response Team is handling the investigation. Representatives from the U.S. Department of Justice and the consent decree monitoring team also responded to the scene.

Police will release more information about the incident at a later time, Smith said.
