Sebastian M., the 35-year-old accused of causing a fatal accident on the A1 highway in September 2023, is currently challenging his detention conditions in Poland. The defendant, who faces up to eight years in prison, has filed a complaint with the Commissioner for Human Rights regarding his treatment in custody.
Background of the A1 Accident
The legal proceedings stem from a tragic collision near Piotrków Trybunalski. A BMW driven by M. Struck a Kia carrying a married couple and their child, leading to a secondary incident where another vehicle hit safety barriers and caught fire.
The collision resulted in the deaths of three passengers, including a 4-year-old child. Following the incident, M. Fled to Dubai but was eventually extradited to Poland in May 2025.
Detention and Safety Measures
M. Is currently being held in an isolation cell at the Piotrków Trybunalski detention center. This placement was implemented for his safety after his lawyer, Mec. Katarzyna Hebda, received an SMS message stating that her client had been hanged.
However, the defendant has expressed significant dissatisfaction with this arrangement. In a note to the court, M. Detailed several grievances regarding his living conditions and access to basic necessities.
Specific Grievances Reported by the Defendant
M. Has complained of poor nutrition, stating his meals consist primarily of bread, margarine, and tea. He also noted a lack of access to books and an absence of recreational, educational, or physical activities.

The defendant further cited environmental issues, including:
- Lighting: Blue fluorescent lamps that he claims cause headaches and eye pain.
- Hygiene: Showers that are reportedly limited to a few minutes twice a week, often without warm water.
- Climate Control: Heating that is allegedly turned off between 8:00 PM and 5:00 AM, requiring him to sleep in heavy clothing.
- Cell Structure: Windows secured with double bars and non-breathable plexiglass, which limits daylight.
Official Response and Next Steps
The Commissioner for Human Rights has intervened in the matter, though the specific details of this intervention have not been disclosed. Arleta Pęconek, a spokesperson for the Prison Service, confirmed that the administration has been analyzing the situation.
The director of the detention center has submitted a position to the District Court in Piotrków Trybunalskim. The response asserts that the current conditions are in full compliance with the regulatory and organizational standards for temporary arrest.
As the trial progresses, the court may be required to weigh the defendant’s complaints against the official reports from the prison administration. The outcome of these grievances could potentially influence the management of M.’s detention during the remainder of the legal process.
