Beth Holloway Twitty, the mother of missing Alabama teen Natalee Holloway, reportedly snuck into a Peruvian jail and confronted the young man who is the prime suspect in her daughter's disappearance.
Local media say Twitty had a hidden camera with her, but that van der Sloot clammed up.
She was then taken into custory herself, the reports say.
According to CBS News Correspondent Kelly Cobiella, the last time Twitty came face-to-face with van der Sloot was the night after Natalee disappeared.
This time, reports say, their meeting was very brief - but dramatic.

Moment Van der Sloot Met Flores Caught on Tape
Van der sloot has been in Peru's notorious Castro Castro Prison for almost four months, charged with the brutal murder of a 21-year-old Peruvian woman, Stephany Flores.
According to Peruvian news agencies, Twitty managed to see him again Thursday.
Van der Sloot has long been the prime suspect in her daughter's disappearance on the island of Aruba five-and-a-half years ago.
Apparently, Holloway snuck into the prison without being identified and carrying a hidden camera, aided by a Dutch TV reporter who's doing a special on Natalee, and spent about five minutes with van der Sloot.
She's said to have started the meeting by telling him she had "no hate in her soul" for him.
Van der Sloot reportedly responded by handing Twitty his attorney's business card and saying he couldn't speak without his lawyer present.
Gossip website Radaronline.com goes further, claiming Twitty asked direct questions about Natalee's disappearance, but that van der Sloot refused to answer.
Twitty's attorney, John Q. Kelly, confirms only that his client is in Peru, saying, "She's a mother, without a daughter. She wants to bring her daughter home."
Peruvian authorities quickly removed Twitty from the prison, and local media say she's being detained by those authorities.
