Oslo, Norway (CNN) -- The suspect in the bombing and mass shooting in Norway believed the terrorist attacks were "horrible," but "in his head (they) were necessary," a man who identified himself as the suspect's lawyer told Norwegian broadcaster TV2. 

Geir Lippestad told TV2 late Saturday that he represented Anders Behring Breivik, who was arrested Friday after twin terror attacks that left at least 92 dead. 

Breivik "is ready to explain himself" in a court hearing Monday, Lippestad said. 

CNN unsuccessfully attempted to contact Lippestad. 

While they have only arrested one suspect, police in Norway have not ruled out the possibility that someone else may have been involved in the explosion in Oslo and a shooting at a youth camp on Utoya island 

"We're not sure it's just one person... based on statements from witnesses, we think there may be more," Acting National Police Chief Sveinung Sponheim said Saturday. 

A 32-year-old Norwegian was detained and charged with terrorism, but police have not officially released his name. Local media have identified the man as Breivik, who has been described as a right-wing Christian fundamentalist. 

"It's very difficult at this point to say whether he was acting alone or whether he was acting as part of a larger network," Sponheim said. 

The suspect has been talking to authorities, but Sponheim described the day-long interrogations as "difficult." 

At least four people are still missing, he said, as investigators continued to search for bodies of victims of the bomb attack in downtown Oslo. 

The fragility of the damaged structures have made it a slow process, he said.  QUESTIONS:
