Staff at the high security Ila prison have taken strict measures to keep Breivik apart from other inmates since his incarceration there in July after the dual terrorist attacks that left 77 people dead.
State-appointed specialists have previously found Breivik to be criminally insane, meaning he will be placed in psychiatric care unless that decision is overturned on appeal.
But none of Norway’s existing psychiatric institutions are considered anywhere near secure enough to house the 32-year-old right-wing extremist, newspaper VG reports.
Not even Dikemark hospital in Asker, home to some of Norway’s most dangerous individuals, is thought to be secure enough to prevent a potential Breivik escape, the newspaper said.
According to VG, health authorities are examining the possibility of constructing a miniature hospital within the confines of Ila prison, where Breivik would stay on as the sole patient.
“It’s correct that we’re looking at a number of options that take into account both his safety and concerns for the protection of the community,” said Secretary of Start Robin Kåss (Labour Party), who declined to confirm specific details.
Breivik has admitted to setting off a car bomb outside government offices in Oslo before gunning down 69 mostly young people at a summer camp on Utøya island on July 22nd last year.
His trial begins in April.
