In addition, the police have also experienced a difficult working relationship with staff at the centre, with blame falling on the Swedish Migration Board (Migrationsverket).

Between 2008 and the present, around 50 individuals have escaped from the centre, according to Göteborgs-Posten (GP) newspaper.

An official working at the centre has also been found guilty of rioting during the EU protests in Gothenburg in 2001.

“We have long questioned the facility’s operations and there have been several strange escapes,” Lars Skoglund, head of the Västra Götaland border police, told GP.

Mistrust between staff and the police came to a head in February. Police suspect a deportation of a Libyan man was sabotaged by centre employees. On a subsequent attempt to deport the same individual, police elected not to inform the staff.

With almost 20 men and a warrant, police arrived at the detention centre to pick up the Libyan. An uproar occurred, one of the reasons being that the facility staff at first refused to open the doors.

They only allowed the police in after they threatened to force their way in. The incident was reported but the case was dropped due to lack of evidence.

Paul Fågelberg, one of the directors of the Kållered detention centre, told TT he maintains total confidence in his staff.
