Union politicians question why CSD attack suspect Abdul B. was free despite known threat

Terrorism expert Rolf Tophoven analyzes the vulnerabilities in the suspected attack in Berlin. He is convinced that the perpetrator deliberately exploited them. At the same time, he warns of the growing threat from the Islamic State.

Following the suspected Islamist-motivated attack on the sidelines of Christopher Street Day (CSD) in Berlin and the death of the suspect, calls for clarification and legal consequences are increasing. The focus is on why the suspected perpetrator was free despite being known to authorities and having a prior conviction.

Political Reactions

Federal Interior Minister Alexander Dobrindt (CSU) commented on the suspected perpetrator, stating:

"We know that he committed a large number of crimes, that he sympathized with terror, that there was also a conviction that was suspended on probation, and that the public prosecutor's office filed a complaint against it."

Speaking to ARD, Dobrindt added:

"And indeed, the question is currently being asked: How can a sentence be suspended on probation for someone identified as a potential threat? This is also being investigated in detail."

In an interview with RTL, he described the probationary sentence as "certainly incomprehensible given this level of threat."

Berlin's Governing Mayor Kai Wegner (CDU) also expressed surprise at the judiciary's handling of Abdul B.:

"He was convicted under juvenile criminal law. And then unfortunately the court issued a probationary sentence. And I don't want to judge that, that's the independence of the judiciary, but words fail me."

Background on the Suspect

The 21-year-old suspect, a German of Lebanese origin, was killed on Sunday evening during a police operation intended to lead to his arrest. According to the Attorney General's Office:

• After unsuccessful attempts to join the Islamic State (IS) in Syria, he was arrested in November 2025 upon his return at Berlin's BER airport, following a three-month prison sentence in Lebanon.
• After a longer period of pre-trial detention, he was sentenced on May 12 by a juvenile lay judge court at the Tiergarten District Court to 22 months of juvenile detention — among other things for preparing a serious act of violence endangering the state.
• The decision on suspending this juvenile detention on probation was reportedly postponed for a period of six months.

Court Decision and Arrest Warrant

According to the Attorney General's Office, the court lifted an existing arrest warrant against Abdul B., "since pre-trial detention primarily serves to secure the criminal proceedings and does not represent an anticipated punishment." The conviction was not legally binding until his death because the Attorney General's Office had filed an appeal, demanding a higher sentence.

As recently as the beginning of this month, search measures were carried out at his address in Berlin-Schöneberg on initial suspicion of violating the Weapons Act. However, only a toy weapon was found. According to Bild, Abdul B. was scheduled to appear for a deradicalization course on Monday.

Expert Analysis

Terrorism expert Peter Neumann from King's College London called for a review of criminal law:

"Overall, our terrorism criminal law is too lenient. The sentences in Germany are too short compared to other European countries. And what also comes into play with us is that we have a juvenile criminal law, which the suspected attacker also fell under."
