Officials announced that a gunman entered the lobby of a psychiatric hospital in New Hampshire, USA, and shot a security guard, but a police officer returned fire, killing him. No one else was injured in the incident, which occurred around 3:30 PM at New Hampshire State Hospital in Concord, the state capital, according to Colonel Mark Hollis of the state police. In a subsequent press conference, Hollis refrained from providing any information about the attacker and added that investigators are still trying to identify him. New Hampshire Governor Chris Sununu wrote on social media that the victim was Bradley Haas, who worked in security at the hospital.
