A man described as "Turkish" went into a hair salon and fired indiscriminately into the packed business killing at least one and leaving one with critical injuries.
Heavily armed police arrived at the scene and discovered one man was already dead and a woman was critically injured – she has been airlifted to hospital.
The shooter, understood to be a 27-year-old Turkish man, is believed to have fired indiscriminately into the bustling hairdressers' shop in Dueren, Germany.
Witnesses report the gunman entered the salon, shouted at a woman and then opened fire, leading regional police spokesperson Ulrich Braun to say: "This may be a crime of passions."
He is reported as having fled to a nearby apartment building having taken a woman as hostage.
