Just before 11 pm on National Day, callers testify to loud bangs and that people were seen running from the university campus in the southern part of the city.
– So far we have no reports of any injured people. Nor are there any suspects at the moment, says Jerker Olsson.
Police have cordoned off an area where they found evidence that there was probably a shooting.
– We are waiting for a search dog that specializes in weapons and gunpowder. And right now there is a knock on the door to gather more information, says Olsson.
The incident is classified as serious weapons offences.
