( CNN ) -- The families of the victims of a mass shooting rampage on a Norwegian island are visiting the scene Friday , a month after two attacks plunged the Scandinavian nation into mourning . Sixty-nine people died July 22 on Utoya island , where hundreds of mostly young people were gathered for a summer camp held by the youth wing of the governing Labour Party . Eight others died in the bombing of Oslo government buildings hours earlier . TV footage showed the first group of relatives of victims of the shooting walking in line as they arrived on Utoya island in the rain . `` It is a very important and emotional day for these families , '' Health Minister Anne-Grete Strom-Erichsen said , according to Norway 's official NTB news agency . A policeman will show each family where their loved one was found after the attack , NTB reported . The families will also be accompanied by Red Cross representatives . Many of the 69 families affected have said they plan to visit the island over the weekend , Norwegian reports say . Meanwhile , a judge ruled that Anders Breivik , the man accused of carrying out both attacks , should be held in solitary confinement for another four weeks because there was a real danger he would otherwise tamper with evidence . This was especially important because the police have still not established whether Breivik had accomplices , Judge Hugo Abelseth said . He told the court in Oslo that the police request for Breivik to remain in isolation outweighed the suspect 's concerns . Breivik , 32 , had told the court that being held in isolation is `` boring , monotonous and a sadistic method of torture , '' the judge said . Breivik appeared in court to hear the arguments but the session was not open to the public or media . He will remain in solitary confinement until September 19 , Abelseth said . At an initial court appearance for Breivik last month , the police were granted eight weeks ' custody , four of them in isolation . Suspects are not normally held in isolation for longer than two weeks in Norway , according to local media reports . Speaking after Breivik 's court appearance , Paal-Fredrik Hjort Kraby of Oslo Police District told reporters that the suspect was being kept cuffed by his hands and feet , and also chained at the waist . He said several survivors of the Utoya massacres had wanted to be present at the court hearing , but that the police had decided it was too risky in case they unwittingly revealed details of the case that would enable Breivik to alter his explanations . The police instead allowed four of the 113 lawyers representing the survivors , victims and their families to be present at the hearing , Kraby said . Survivors may be allowed in court when the investigation is no longer at such a sensitive point , he said . Kraby also responded to questions about the revelation by police Thursday that Breivik had made two calls to the police while on Utoya island on July 22 . Officers had not called Breivik back because they say no number came up on their display . The most likely explanation for this is that the phone was not equipped with a SIM card or subscriber identity module , Kraby said , which would have transmitted the phone 's number . Police chief Sissel Hammer on Thursday confirmed that Breivik had made two calls , one to Nordre Buskerud district and another to Sondre Buskerud Police district . According to a police transcript of the calls , Breivik said : `` Hello , my name is commander Anders Behring Breivik of the Norwegian anti-communist resistance movement . '' After the police operator responded , he said : `` I am at Utoya . I wish to surrender . '' Kraby said Breivik had been questioned for a total of 60 hours . He has not been questioned this week but questioning will resume next week . It is too early to tell what the final charges against Breivik will be , Kraby added , as the police are still systematically collecting and evaluating evidence and information . Breivik 's lawyer said his client was concerned about appearing smart and respectably dressed for Friday 's court appearance , state broadcaster NRK reported . During the past four weeks in solitary confinement , Breivik has been given more clothes , a clock and books , as well as a computer that is not connected to the internet , NRK said . He has not had been allowed any visitors , letters or media access . Breivik was taken back to Utoya -- which remains a crime scene -- on Saturday as part of a police investigation into the rampage . Police said they spent nearly eight hours questioning Breivik and walking with him around the island during a reconstruction of the attack . They said he `` was not emotionally unmoved , '' but did not express remorse during his return to the scene . Breivik has been held in solitary confinement since he was taken into custody on the island on July 22 . He has admitted carrying out the attacks , his lawyer and a judge have said , but has pleaded not guilty in court . The ages of the 77 people killed in the twin attacks ranged from 14 to 61 , with an average age of 21 , the government said . CNN 's Cynthia Wamwayi and journalist Olav Mellingsaeter contributed to this report .

He says isolation is ` ` boring , monotonous and a sadistic method of torture '' He is accused of carrying out twin attacks a month ago that killed 77 .
