Suspect was classified as a person with potential risk for several months last year. The 21-year-old is suspected of attempting to maliciously murder two elementary school children at the end of February.
The nine and ten year old children were seriously injured by knife wounds. He is also said to have announced a murder to a witness in Bavaria in a chat. However, the police in Duisburg did not receive this information in time. The supervisory authority will examine whether the accused should have been reclassified in view of these incidents.
