At least nine people were killed during a shooting committed by an 18-year-old German-Iranian man, police chief Hubertus Andrae said Saturday.
Andrae said that materials on previous mass shootings were found in the gunman's room. He said that there were no indications the assailant was linked to the Daesh terror organization.
Three of the nine victims killed were Turkish, said Turkey's Foreign Minister Mevlüt Çavuşoğlu on the same day.
Munich prosecutors said the shooter had been in psychiatric care and was treated for depression. The attack appeared to be a 'classic shooting rampage' and not related to terrorism, a prosecutor said.
A police investigator said that the man was carrying a 9mm Glock pistol along with 300 rounds and a red rucksack when he started shooting in a McDonald's restaurant at 5:52 pm (1552 GMT) at the Olympia shopping centre in Munich.
There are children among the victims and three of the 16 people injured in the shooting remain in critical condition, Andrae said.
Two men initially suspected as accomplices in the shooting who had left the scene in a car were later interviewed and cleared, police said.
The teenager, who held dual German and Iranian citizenship and had lived in Munich for more than two years, shot himself dead about 1 kilometre away from the shopping centre. His rucksack was examined for explosives, but police did not say whether any were found.
The shooting triggered a series of evacuations and a widespread state of panic across the southern German city. Public transportation was temporarily suspended and residents were asked to remain inside their homes.
The Bavarian parliament and rail operator Deutsche Bahn were among those to open their doors to residents unable to reach their homes for cover.
