Police in Munich have said that a German-Iranian teenager who shot dead nine people and then killed himself in the city on Friday had no known links to the Islamic State group, according to German media reports.
Police spokesman Peter Beck has said that officials didn’t yet know what triggered the crime but there was no clear political motivation.
Officials have also said that the 18-year-old had received psychiatric care for depression and was most probably a lone gunman.
They added that newspaper clippings and books related to killing sprees have been found during searches at the shooter’s family apartment that followed the shooting.
The attack at the Olympia shopping mall left 27 people injured, of whom 10 were in a critical condition on Saturday.
