Norwegian police say a failed asylum seeker from South Sudan, suspected of killing three people on an express bus the day before, has been moved to a psychiatric clinic for evaluation.
The alleged motive was not known because the man, age 30, had yet to be interviewed by police, they said on Tuesday.
"The police have planned for a custody hearing this week, but I don't have any other details," his attorney, Fredrik Verling, told broadcaster NRK.
The man was moved to the clinic in Bergen after being treated for minor cuts.
His flat, which he shares with several other asylum seekers in the small town of Ardal, has been searched.

Ronny Iden, police chief in the Sogn and Fjordarne district, and police prosecutor Jorn Lasse Refsnes, told reporters the motive for the attack remained unknown. They did not know whether the suspect had been aware that he was due to be deported from Norway on Tuesday.
The victims were a 19-year-old woman and two men in their 50s. One of the men was the Norwegian driver of the bus; the other was a Swedish passenger. The three apparently died from stab wounds.
Forensic tests also were due on a knife found on the Oslo-bound coach.
Tor Brekke, deputy head of the asylum center in Ardal, said the man's asylum request recently had been rejected.
Brekke told broadcaster NRK the man had been due to be sent back to Spain, where he had initially applied for asylum.
Ten years ago, a driver on the same coach service, Valdresekspressen, was stabbed to death by an asylum seeker from Ethiopia. The attacker was later ordered into psychiatric care.
