The suspect was last seen travelling west on Shuter Street, they added.
While the suspect’s age isn’t known, Marsman said he appeared to be in his 30s or 40s.
Marsman said police have no information suggesting the two men knew each other, although he said it wasn’t a completely random attack given there was an interaction outside the clinic.
“There was some sort of aim to his approaching this person, but I’m not ready to discuss that,” Marsman said. “We are eager to get this person into custody as quickly as possible …We don’t have a name yet. If anyone does know this person or recognize him, please give us a call.”
Anyone with information about the suspect is asked not to approach him, but to contact investigators.
