According to the police, the death driver in Berlin had mental problems in the past.
"The exact circumstances still have to be clarified as part of the ongoing investigations," said Berlin's Interior Senator Iris Spranger (SPD) on Thursday in the House of Representatives.
The now 29-year-old man of Armenian origin was naturalized in Germany in 2015.
He was noticed by the police several times, there had been investigations into bodily harm, trespassing and insult.
Nothing is known about political and extremist acts.
"Even in connection with anti-constitutional efforts, the suspect has not been noticed so far." Spranger said no confession letter was found in the car.
“Posters were found in the car.
Whether and to what extent these are related to the crime is also the subject of the investigation." Spranger emphasized: "Therefore, based on the current status, I rate yesterday's events as a rampage by a mentally impaired person."
The man is in police custody and will be brought before a judge on Thursday, Spranger said.
The judge can issue an arrest warrant so that the man is remanded in custody.
“The investigations are being conducted by the homicide squad and are in full swing.
The on-site measures have been completed.” The police searched the man’s apartment on Wednesday evening.
"Currently, both mobile phones and computers are being studied very intensively."
Spranger continued: "I hardly closed my eyes tonight." Her thoughts are with the teacher who was killed and her relatives, as well as with the many injured and seriously injured.
Some of the young people and parents who came to Berlin on Wednesday are now on their way back to Hesse.
After Chancellor Olaf Scholz and Berlin Mayor Franziska Giffey, Federal Minister of the Interior Nancy Faeser (all three SPD) also visited the scene on Thursday.
The driver had raced on Wednesday morning at the Memorial Church over the sidewalks of Ku'damm and Tauentzienstrasse.
A woman died, 29 people were injured according to the current status, 6 of them critically and 3 seriously.
Among them were many 10th graders from Hesse.
