Bavaria’s interior minister, Joachim Hermann, said the Syrian man who blew himself up in the attack had pledged allegiance to the group calling itself Islamic State in a video message found on his mobile phone.
Mr Hermann said two phones, multiple SIM cards and a laptop were found with the body of the 27-year-old asylum seeker or at his accommodation and video shows him threatening a ‘revenge attack’.
Fifteen people were injured in the attack, outside a wine bar near to where a music festival was taking place.
According to reports, the man had tried to get into the festival but was turned away because he did not have a ticket. He then blew himself up outside.
Bavarian authorities said that the bomb was clearly meant to kill as many people as possible.
Further bomb-making equipment was found at the asylum seeker accommodation where the man was living.
