Between 150 and 200 demonstrators managed to force a police line on Södra vägen near Stadsparken in the centre of the university town. The demonstrators, taking part in an “occupation festival” then stormed towards the old hospital area of St.Lars.
At 3.20pm police responded and forced their way into the larger of the two occupied buildings. Two police officers climbed up to the roof where three activists sat apparently chained to the chimney, according to news agency TT.
St.Lars hospital was a psychiatric hospital whose operations have since been merged into Lund University Hospital. Some of the buildings remain in use.
Some of the young activists broke into one of the empty hospital buildings and shortly after into another 150 metres away. The activists then spread out through the underground system of passages that link the buildings.
By 7.30pm police had managed to regain control of the buildings and confirmed that 90 people had been detained.
The so-called occupation festival was held in Lund on Saturday organized by left wing youth groups. The university town has seen wave after wave of demonstrations since the autumn, with students and other young people protesting against a lack of housing.
More than 200 police were deployed on Saturday to monitor the situation and 26 people were detained after clashes with police. Several are suspected of rioting.
