On 4 February 2025, a school shooting occurred at Campus Risbergska, an adult education centre in Örebro, Sweden. Around 10 people have been killed, including the perpetrator, and 15 injured; a motive behind the attack is being investigated by the Swedish Police Authority and the Swedish Security Service.

Six people were hospitalised, with authorities warning there may be more casualties. According to Swedish prime minister Ulf Kristersson, it is the worst mass shooting in the country's history.

In 2021, Sweden ranked 11th in Europe for gun-related homicides. In addition, the country has the highest rate of gun violence per capita in Europe, according to figures from 2023. Swedish authorities have worked to combat gun violence in recent years due to an increase in gang-related shootings.

Campus Risbergska is a komvux, an adult education centre mainly attended by people who have not completed primary or secondary school. Located in Örebro in central Sweden, the school shares a campus with several other educational institutions. At the time, around 2,000 adult students were enrolled at the school, which offers courses at the gymnasium level, as well as Swedish for immigrants.

Officers were called around 12:33 p.m. local time (11:33 UTC). Two teachers at the school told Dagens Nyheter that they heard gunshots from a corridor, followed by silence for a half-hour, and then more shooting. The perpetrator and police exchanged gunfire but no officers were injured.

Maria Pegado, a teacher at the school recounted hearing the shots fired and escaped with her 15 students through the hallway. Ingela Bäck Gustafsson, the school's principal, was eating when students ran in and told everyone to evacuate; she and others took shelter in the staff room of Myrorna, a nearby second-hand store. Lena Warenmark, another teacher at the school, said that fewer than usual students were in the building at the time of the shooting since many had gone home following a national exam.

The Swedish Police Authority stated that the suspect is believed to have acted alone, and has been confirmed dead in the shooting.

Nearby schools were put into lockdown and police instructed the public to stay away from the area, and soon cordoned off the area. Ambulances were sent from the neighbouring counties of Södermanland and Västmanland to assist medical personnel in Örebro, while Värmland sent blood. In addition, Värmland and Dalarna provided police reinforcements. At least six people were taken to Örebro University Hospital, five of whom had gunshot wounds. The Örebro municipal government provided support following the shootings, setting up a crisis centre at a church.

The suspect's residence in Örebro was barricaded by the police. TV4 reported that the man had a firearms license and had no prior criminal convictions. Police believe the perpetrator acted alone, and ruled out terrorism and gang-related crime as motives.

Swedish prime minister Ulf Kristersson commented on social media that it is "a very painful day for all of Sweden", and urged an investigation into the shooting. Swedish Justice Minister Gunnar Strömmer, commented "The information about the violent attack in Örebro is extremely serious." In a press conference, Strömmer referred to the shooting as "one of the worst shootings in Swedish history".

Carl XVI Gustaf, King of Sweden, sent condolences, saying, "We send our condolences tonight to the families and friends of the deceased. Our thoughts at this time also go to the injured and their relatives, as well as to others affected." A number of local politicians and world leaders also sent condolences.

Roberto Eid Forest, head of the local police, described the scene as "awful, exceptional" and "a nightmare".
