Munich Shooting: 'A quiet guy, no criminal record' - everything we know about the gunman on Saturday morning
Munich police said the shooter in a deadly shopping mall rampage was an 18-year-old German-Iranian man whose motive was "completely unclear
"The perpetrator was an 18-year-old German-Iranian from Munich," police chief Hubertus Andrae told reporters after the massacre on Friday that left 10 people dead including the gunman.
"The motive or explanation for this crime is completely unclear."
Mr Andrae said the shooter - who opened fire at a busy shopping centre near the southern German city's Olympic stadium before turning the gun on himself - had dual citizenship and "no criminal record". He said inquiries suggested the suspect had lived in the city for more than two years.
His body was found less than a mile from the mall.
A video appeared to show a gunman on the roof of a parking garage as he exchanged insults with people on a nearby balcony who referred to him a foreigner.
"I'm German, I was born here," the assailant is heard to reply.
An onlooker then calls him a "w*****" before the gunman tells the man to “shut your trap” and more shots are fired.
The gunman also apparently claimed to have been "bullied for seven years".
Police commandos, armed with night vision equipment and dogs, raided an apartment in the Munich neighbourhood of Maxvorstadt early on Saturday where the German newspaper Bild said the gunman lived with his parents.
"He lived right next to me," Bild quoted a neighbour as saying. "A friend of mine went to school with him and said he was rather a quiet guy. He recognised him from the videos from the scene."
German Foreign Minister Frank-Walter Steinmeier also said the motive for the attack was not yet clear.
"The motives for this abhorrent act have not yet been completely clarified - we still have contradictory clues," German Foreign Minister Frank-Walter Steinmeier said in a statement.
While police initially called the mall shooting an act of terrorism, they said they had "no indication" it involved Islamic extremism.
US intelligence officials, speaking on condition of anonymity, said initial reports from their German counterparts indicated no apparent link between the shooter and Islamic State or other militant groups.
