ORANJESTAD, Aruba (CNN) -- An Aruban judge, the father of a 17-year-old suspect in the disappearance of an Alabama teenager, has also been arrested in the case, a prosecution spokesperson said Thursday.
Paul Van Der Sloot is now being viewed as a suspect in the case of Natalee Holloway, a missing 18-year-old from suburban Birmingham, Alabama, Mariaine Croes said. He was arrested about 2 p.m. Thursday.
On Wednesday, Holloway's mother said more individuals "need to be pursued" in connection with the case.
Beth Holloway Twitty said she's sure the four young men in custody -- but not formally charged in the case -- have more information to divulge.
"I have no doubt that they know what and who and where and when and why and how. I have no doubt," Twitty said on NBC's "Today Show."
"The only thing I think there are some other individuals, though, that need to be pursued, and I know the local authorities are doing that and will be doing that," she added.
