FIRST PICTURE - Munich maniac was 'mentally ill loner obsessed with shooting sprees': Iranian-German killer, 18, had 300 rounds of ammunition in rucksack as he went on murderous rampage which ended with nine dead before he killed himself

Police have said today that the 18-year-old loner who gunned down nine people during a rampage through Munich last night was deranged and obsessed with guns, but had no links to ISIS. They said Ali David Sonboly (centre) had no known links to Islamic State. Police who searched his room (bottom right) found newspaper clippings on attacks including an article entitled 'Why do students kill?' His father works as a taxi driver and his mother works in German department store Karstadt. Police are investigating a fake Facebook advert which offered free food at the McDonald's (top left), where he killed the first of his nine victims with a 9mm Glock pistol. Terrified shoppers were seen running for their lives from the Munich Olympia Shopping Centre after hearing gunshots (bottom left). Witnesses said that the gunman screamed 'I'm German' and 'Allahu Akbar' before shooting at children. A total of 21 people were taken to hospital as a result of the incident - ten are fighting for their lives in critical condition and 16 are still receiving medical treatment.
