Ten days before the attack, Mr Daleel had received notice from the German authorities that he was to be deported to Bulgaria.
Under the Dublin regulation, refugees are required to claim asylum in their first port of entry into the EU. Mr Daleel crossed into Bulgaria from Turkey in 2013. He later claimed he had been abused in detention in Bulgaria.
The psychological assessment of Mohammed Daleel, seen by BBC Newsnight, was written by Axel von Maltitz, a trauma therapist in the town of Lindau. Mr von Maltitz treated the 27-year-old Syrian for psychological problems until January 2016.
He believes the deportation notice triggered Mr Daleel's attack. "That is always what he promised. That was always his reaction as answer to the information that he was to be deported.
"I warned them. That is what I wrote. 'Be careful if he has to be deported to Bulgaria'." Axel von Maltitz first met Mohammed Daleel in January 2015, after the Syrian had cut his wrists following an earlier deportation order.
"He had bandages around his arms because that was still quite fresh. He was highly traumatised. "Traumatisation has very typical symptoms. He had Post Traumatic Stress Disorder severely. Very strong."
Mr Daleel claimed he was an opposition activist in Syria and that he had been imprisoned and tortured on three occasions between 2008 and 2011.
