Mohamed Addamrou is wanted for the murder of Sergeant Mateusz Sitek. An arrest warrant has been issued for the murderer from Morocco, and pre-trial detention has also been ordered in absentia. Despite this, the prosecutor’s office and the Military Police refuse to publish the criminal’s image. Meanwhile, in the justification for the decision to issue a European Arrest Warrant, the court stated that the wanted man may be staying within the European Union. The investigation, however, has been suspended because the Belarusian authorities have failed to respond. So, where is the killer of the Polish soldier?
Twenty-one-year-old Mateusz Sitek, a soldier of the 1st Warsaw Armoured Brigade, was serving on the Polish-Belarusian border. On the night of May 28, 2024, near the village of Dubicze Cerkiewne, a group of attackers cooperating with the Belarusian services launched an assault. One of them stabbed the soldier with a knife. Severely wounded, he was taken to the hospital. A few days later, on June 6, Sergeant Mateusz Sitek died.
According to the Warsaw District Prosecutor’s Office, which is conducting the investigation, the killer is Moroccan national Mohamed Addamrou. More than two years later, the murderer remains unpunished.
“The investigation in this case was suspended on May 22, 2026, due to a long-term procedural obstacle, namely the suspect’s stay outside the borders of the Republic of Poland,”
prosecutor Piotr Skiba recently stated.
European Arrest Warrant after a year and a half
The European Arrest Warrant was issued only around a year and a half after the crime. What is more, the justification issued by the Regional Court in Białystok shows that investigators are considering the possibility that Addamrou may be in one of the European Union member states.
Despite this, we did not find his name in the public wanted-person databases of the Polish National Police Headquarters, Interpol, or Europol.
The same first and last name
A social media profile attributed to Mohamed Addamrou still exists online. It leads through Morocco, Russia, and Belarus. Analysis of these traces points to links with a university in Agadir, a stay in Voronezh and Moscow before the events at the border, and a disappearance from social media after June 2024.
An analysis of publicly available materials posted on social media makes it possible to outline the story of a person bearing the same first and last name. Although the prosecutor’s office refused to confirm that the Facebook profile found online belongs to the Moroccan man wanted by Poland, a series of similarities means that these digital traces deserve attention.
In Russia
The most interesting element of the profile is the clear Russian trail that appears long before the events on the Polish-Belarusian border. In one photo published in October 2023, a young man can be seen posing against the backdrop of St Basil’s Cathedral in Moscow. Voronezh is also listed on the profile as a place of stay. This would mean that a person bearing the surname Addamrou was in Russia at least eight months before the attack on the Polish soldier.
This is particularly significant in the context of the official findings of the investigation. It confirms that “immigrants” were being used by both the Belarusian and Russian services, provided that the profile does indeed belong to the person sought by the prosecutor’s office.
A university in Morocco
The account under analysis contains references to Ibn Zohr University in Agadir, one of the largest universities in Morocco. This is consistent with information from the prosecutor’s office, which indicates that the suspect is a Moroccan citizen. Among the photos published on the profile are also images of a young man who appears to be in his early twenties.
In November 2025, meanwhile, a post concerning Mohamed Addamrou appeared in the group “Marocchini A Bruxelles,” which brings together Moroccan emigrants living in Belgium. The author asked for help in establishing the man’s fate, providing his full name, his age, 22, and information that he was allegedly detained on June 11, 2024, in Lida, Belarus. The post also stated that his mother had had no information about her son for a long time and was trying to find out what had happened to him.
He went silent after the crime
The activity of the account itself is equally interesting. Analysis of publicly available materials indicates that after June 2024, the profile practically went silent. No new photos, travel updates, or posts appeared that would make it possible to trace the subsequent fate of the account’s owner.
