A gunman opened fire at a market in the town of Trelleborg, Sweden, injuring at least four people, Sweden's Aftonbladet reports. Police first responded to reports of a shooting at a market in Trelleborg, in the Ehrenbuschsgatan area. Four people had to be been transported to nearby hospitals, according to a Swedish police report. The incident is not being treated as a terror attack by Swedish authorities, police said Thursday.

?The area is known to have incidents of gang violence, according to social media users.

A police spokesman confirmed to Express that police were investigating reports of a shooting, and that an area around the crime scene has been temporarily closed. At 22:30, the police received several calls about a suspected shooting in central Trelleborg, which has a population of about 40,000, according to local media reports.

Speaking to local media, a police spokesman clarified that only two of the injured people sustained gunshot wounds, while the other two hospitalized patients "have other types of injuries."

"We have received several reports of a shooting in Trelleborg," a police spokesperson was quoted saying by UK media.

"We have received several reports of a shooting in Trelleborg. We were quickly on the spot and found that, within a fairly limited area, we find more people with suspected shot injury. We are blocking certain areas and will conduct an investigation. I do not have any more information at this time. But we are at the scene and investigating."

Police said several people were injured at different locations. The police spokesman, Fredrik Bratt, added that multiple victims suffered “suspected gunshot” wounds and that "a major operation was underway."

“There were many shots. We saw someone running outside,” an eyewitness told the Swedish publication Expressen.

“I was at home at the computer when I heard a loud bang,” Aron Tydén – another person in the area – told the publication, claiming that he heard people running.

Police have cordoned off the area, allowing ambulances through. The victims were reportedly rushed to hospitals in Malmö and Lund. Forensics team and a canine unit have also been dispatched to the scene of the incident.

The southern Swedish town hosts a population of approximately 40,000 residents. In July, three people were shot in the nearby city of Malmo, Sweden. After being hospitalized, it was reported that each injured person had been known by police for their involvement in drug trafficking.
