BOSTON - The sister of "Survivor" winner Richard Hatch says she thinks her brother was sent back to jail because he granted an interview.

Kristin Hatch told the U.S. television program "Today" on Wednesday that when a sheriff's deputy came to bring her brother to the Barnstable County Jail in Massachusetts on Tuesday, she overheard him say that Hatch was being jailed because "he did an interview."

"Today" show host Matt Lauer and Hatch both said they had received permission from the federal Bureau of Prisons to do the Tuesday interview, in which Hatch said he believes the judge in his tax evasion case discriminated against him because he's gay. He also accused a prosecutor of misconduct.

A Bureau of Prisons spokeswoman couldn't immediately be reached Wednesday.

Hatch, 48, had been staying at his sister's Newport, Rhode Island house with a monitoring device while on home confinement. His arrest came three months after he was released into home confinement and just hours after he spoke publicly for the first time since he got out of federal prison.

Hatch's lawyer, Cynthia Ribas, said Wednesday she still had not been given an explanation as to why he was arrested.

Hatch was convicted in 2006 for not paying taxes on the $1 million prize he won on the CBS reality show's first season. He was sentenced to extra prison time for lying on the stand.

He told a U.S. television program that he has been financially devastated by his tax case.
