The preliminary investigation into suspected poisonings at Akademiska Hospital in Uppsala has been closed completely, prosecutor Emma Häggström confirmed. Four employees on the same department at the hospital fell ill, and police suspected they had been poisoned. Häggström stated the prosecutor decided to close the investigation because it cannot be proven that the person who was suspected committed the crime, and further investigative measures are not expected to change the evidence situation. No crime can be proven in the poisoning case, according to the prosecutor. The specific substance or method used in the suspected poisonings remains unknown.
In December, a woman in her 60s was arrested and remanded on probable suspicion of poisoning four people at the workplace in October and November, according to multiple reports. The woman was released a week later when the district court did not consider the evidence sufficient to keep her detained, official sources indicated. In February, she was dismissed from her position, multiple reports confirm. According to Uppsala Nya Tidning, security chief Viktor Ekström at Akademiska Hospital described having expected the investigation to lead to an indictment and expressed disappointment it is closed.
Prosecutor Emma Häggström explained the decision was based on the inability to prove the suspect's guilt and the expectation that further investigation would not alter the evidence. According to Uppsala Nya Tidning, Viktor Ekström described his disappointment, having anticipated an indictment from the hospital's security perspective.
In a separate case, police are closing the preliminary investigation into arson at the tennis hall in Arvika, according to preliminary investigation leader Jonas Wendel. In October, Arvika was awakened by the tennis hall burning down, official sources reported. Wendel stated the investigation into the arson is not progressing further at the moment, but police are open to continuing if new information emerges.
The prosecutor decided to close the investigation because it cannot be proven that the person who was suspected committed the crime, and further investigative measures are not expected to change the evidence situation.
The investigation into the Arvika tennis hall fire was extensive but inconclusive. About seventy people have been interviewed, the National Forensic Center has investigated various leads, and police have reviewed hours of surveillance camera footage in the arson case, but without results. The police conducted an extensive technical crime scene investigation, research indicates. That technical investigation could not answer how and where the fire started, according to research sources. The National Forensic Center examined various traces and objects, research shows. The exact cause and origin of the fire remains undetermined despite these efforts.
Police findings and hypotheses provide some clues but no definitive answers. The police hypothesis is that the fire was set and started inside the hall, according to Jonas Wendel, preliminary investigation leader at the Police in Arvika. Remains of motor gasoline have been found in several places, research indicates. The gate to the south was open when the fire broke out, and it can only be opened from the inside, research shows. The gate may have been unlocked without this being noticed because a thick mat covered it, as it is locked with a bolt, according to research. The identity and motive of the person(s) responsible for this arson are still unknown.
Investigators faced significant challenges in determining the fire's progression. The police cannot determine the fire progression or where the fire started because it was explosive and quickly destroyed the hall, research indicates. It is often difficult to see a more exact fire progression in such a total fire, research sources note. The police want to know if anyone saw any unauthorized person or anything else suspicious in the hall between August 18, 2025, when the gate was last used, and October 10, 2025, according to research. They also want to contact people who had a fire in the shelter nearest the hall in Styckåsskogen the evening before the fire, research shows. All information that can help clarify the course of events is of great value, research indicates.
The fire had a substantial impact on the Arvika community. The tennis hall was frequently used by many members and served a large social function in the community, research shows. The closure of the area was necessary because there was a fire in the tennis hall near the school with heavy smoke development as a result, research indicates. Carina Johannessson, elementary school principal in Arvika, urged parents who could to keep their children home that day, according to research. She noted that if one did not have the possibility, after-school activities would be conducted at Gateskolan, research shows.
Security chief Viktor Ekström at Akademiska Hospital had expected the investigation to lead to an indictment and is disappointed it is closed.
In Norway, police have closed one of two cases related to two fires in the same apartment building in Fauske, according to multiple reports. The second fire case is now closed due to insufficient evidence, multiple reports indicate. Police prosecutor Anna Westermann stated the case is closed because insufficient evidence has emerged to prove the person is guilty of the fire.
Details of the two Fauske fires reveal a complex situation. The first fire occurred in November last year, and a man was charged with setting fire to one apartment, multiple reports confirm. That man was remanded in custody because he explained in interrogation that he set fire to the apartment because he could not buy it due to pre-emption rights, according to multiple reports. Four days later, there was another fire in a different apartment at the opposite end of the building, burning the rest to the ground, multiple reports indicate. A man in his 50s was charged with violation of the Fire and Explosion Protection Act for the second fire, according to multiple reports. Police believed the man had moved back into his apartment and that same evening lost a glowing cigarette in the sofa, multiple reports state. Whether there is any connection between these two fires remains unknown.
The first fire case in Fauske is still under investigation, according to multiple reports.
In Sweden, police have initiated a criminal investigation following a fire in a carport in central Östersund, multiple reports indicate. The fire site is still cordoned off, and police are checking surveillance cameras for anything interesting, according to multiple reports. On Wednesday morning, the duty preliminary investigation leader confirmed police have initiated a preliminary investigation regarding suspected arson, multiple reports state.
Initial findings from the Östersund investigation suggest possible causes but no conclusions. A New Year's rocket is believed to have caused a fire, according to multiple reports. The investigation has used police dogs and criminal technicians at the fire scene, research indicates. Whether this fire was intentionally set or accidental remains undetermined at this stage.
Regarding the status of closed investigations, Jonas Wendel noted the police are not progressing further at the moment. He added that the preliminary investigation can be resumed if new circumstances arise. The police want to continue to contact people who can provide information about the incident, research shows.
