FRANKFURT, Germany (AP) — A 29-year-old German police officer has died of injuries suffered during a knife attack that left five other people injured on the central square of Mannheim, officials said Sunday.

The officer was stabbed several times in the head and neck by a 25-year-old immigrant from Afghanistan and underwent emergency surgery after the attack Friday, officials said. The officer was placed in an artificial coma but succumbed to his injuries on Sunday.

Chancellor Olaf Scholz posted on X, formerly Twitter, that he was “deeply grieved” and that the officer’s “commitment to the safety of us all deserves the highest recognition.”

Two dozen of the officer’s colleagues paid tribute to their fallen comrade, removing their hats during a gathering Sunday at the site of the attack

The suspect was shot and wounded by another officer; he remained hospitalized and a judge has ordered him held on suspicion of attempted murder. Police and prosecutors have not provided a motive for the attack, saying the suspect was not in a condition to be questioned.
