A man was stabbed inside MedStar Harbor Hospital in Baltimore on Tuesday afternoon amid a dispute with another man, police said.
Baltimore police said the stabbing victim's wounds were superficial, that his injuries were being treated and that police had a person of interest in custody. No one else was injured.
Baltimore police spokesman Anthony Guglielmi said the men had some prior knowledge of each other, but investigators were working to determine further details. The hospital was never locked down, he said.
"No one else was ever in any peril," Guglielmi said.
