Update, 8:15 a.m.: The sister's name is Elizabeth Breivik, and she lives in Century City with her family. KNX news radio is reporting that neighbors spotted the feds entering Elizabeth's home last night — possibly for questioning — and that the family left soon after. However, there does seem to be activity inside the house again this morning.

Witnesses told CBS2/KCAL9 that a Century City woman who might be the sister of accused Oslo terrorist Anders Behring Breivik was paid a visit by authorities over the weekend, though the purpose of what was reported as questioning wasn't entirely clear.

Anders Behring Breivik, alleged to have killed 93 people with bombs and bullets in Norway last week, mentioned Los Angeles in a “manifesto” that came to light after the attack.

Here's what he wrote about L.A. and the sister:

… [She] lives in los angles, and has chosen a life where … you guessed it: the acquisition of wealth is the driving force in her life.

Breivik says his sis moved here about 14 years ago.

The 32-year-old's manifesto is titled, in part, “A European Declaration of Independence” and rambles into odd corners of his mind, including his view of Muslim “gangs” and plans to pay for sex with a prostitute.

Authorities believe his rage was fueled in part by a right-wing, Christian fundamentalist stance against Muslim immigrants.

Most of those killed were at a youth summer camp in Oslo.
