The number of people injured rose to 35 after a deadly rampage at a Munich shopping centre allegedly by a teenager obsessed with mass shootings, German police said Sunday.
The number included people hurt when panic broke out in the city centre after the shooting at the Olympia shopping mall, a spokesman in Berlin said. Saturday reports put the number of injured at two dozen.
The 18-year-old German-Iranian suspect was an avid reader of books and articles about mass killings including the Norway attacks, which occurred five years earlier to the day, police said.
Most of his nine victims were teens from Turkish and Kosovar immigrant families.
Witness accounts and smartphone footage of the attack indicate the suspect may have harboured resentment towards foreigners even though he was the German-born son of Iranian asylum seekers.
Police said the alleged shooter, armed with an illegal semi-automatic pistol, apparently tried to lure people to the McDonald's restaurant where many were shot by offering free meals via a fake Facebook offer.
Investigators were still determining his motive, but prosecutors and Interior Minister Thomas de Maiziere said the teenager had been treated for depression and that he may have been bullied by peers.
A search of the suspect's home revealed literature including a German translation of the book Why Kids Kill: Inside the Minds of School Shooters by US psychologist Peter Langman.
Chancellor Angela Merkel expressed her deep sorrow about the shooting after convening the National Security Council in Berlin on Saturday.
