The explosion
At approximately 10:36 p.m. on September 24, 2016, an explosive device detonated outside a vacant commercial space on Teréz Boulevard near Király Street, one of central Budapest's busiest corridors. Two police patrol officers were passing the location when the blast occurred. Contemporary court and news accounts describe both officers as suffering life-threatening injuries, with one officer particularly badly wounded.
The device was homemade and designed to project dangerous fragments. The attack occurred on a weekend night in a densely used part of Budapest, creating an obvious risk not only to the two officers but also to other people nearby. The officers survived after emergency treatment.
The investigation
The bombing triggered an extensive national investigation. Authorities collected surveillance footage, forensic evidence and witness information, while police publicly sought help identifying the person seen near the scene before the explosion.
On October 19, 2016, investigators arrested P. László Gergely in Keszthely in western Hungary. Reporting on the prosecution case described forensic links, digital evidence and statements made during the investigation. Prosecutors argued that he had deliberately targeted police officers in order to obtain their service weapons.
The accused made an incriminating statement during the investigation but later withdrew it and denied responsibility during the trial. His mental condition was examined by experts, and the courts found him criminally responsible.
The first-instance judgment
On September 12, 2018, the Budapest Metropolitan Court sentenced P. László Gergely to life imprisonment. The first-instance judgment found him guilty of offenses including aggravated attempted murder and crimes connected with explosives and terrorism. The court initially set the earliest possibility of parole after 25 years.
The fact that the officers survived did not reduce the case to a minor explosives offense. The court treated the attack as an intentional attempt against multiple people, taking into account the planned nature of the bombing and the grave injuries inflicted.
The final 2019 judgment
On March 12, 2019, the Budapest Court of Appeal issued the final second-instance judgment. It upheld the core finding that P. László Gergely had carried out the bombing and imposed life imprisonment. The appellate court increased the minimum period before possible conditional release from 25 to 30 years.
The final judgment included attempted murder against multiple victims, attempted terrorist offense and other crimes. The court's official communication emphasized that the attack had been prepared and executed by the defendant and that the two police officers were deliberately targeted.
The later retrial attempt
In 2023, defense counsel filed a request to reopen the case. The application relied on private expert opinions addressing matters such as surveillance footage, the explosive device, forensic traces and aspects of the defendant's earlier statements. The defense argued that the materials justified acquittal or a substantially lighter outcome.
The Budapest Appellate Chief Prosecutor's Office asked the court to reject the request, arguing that the proposed materials did not amount to genuinely new evidence capable of overturning the findings already examined in the original proceedings. In September 2023, the Budapest Court of Appeal rejected the retrial request, concluding that the submitted opinions did not provide decisive new evidence sufficient to undermine the final judgment.
Defense representatives said they would continue seeking review. The reviewed reliable record does not show the 2019 conviction being vacated. Accordingly, this archive continues to classify the case as Solved / Adjudicated.
Victim impact and later reporting
The two officers survived, but later reporting has described lasting physical consequences from the explosion. Their survival is central to the legal classification: the case concerns attempted murder rather than completed homicide, despite the severity of the attack.
Crime coverage sometimes refers to the incident primarily through the identity of the convicted bomber. This dossier instead centers the documented event, the officers who were harmed, the evidence tested in court and the legal outcome.
