Richard Hatch

Former Survivor winner Richard Hatch is back behind bars, and his sister and attorney say he was jailed for doing an interview.

Hatch, who is under house arrest at his sister Kristin's Newport, R.I., home, was taken into custody Tuesday and transferred to Barnstable County Correctional Facility in Bourne, Mass. It happened hours after the airing of a Today interview in which he said he thinks he was imprisoned in his tax evasion case because he's gay.

"I heard [the sheriff] tell Rich that he did an interview, and that's why he was going back to prison," Kristin Hatch said on Wednesday's Today.

Hatch also accused a prosecutor of misconduct in Tuesday's interview — his first since serving more than three years in jail. He told Matt Lauer that he had proper approval from the Federal Bureau of Prisons to do the interview.

Hatch's attorney, Cynthia Ribas, said on Today on Wednesday that she had secured clearance from the BOP for the interview and still had not been given a reason for the arrest. Ribas said she also pre-approved interviews Hatch did after Today for Access Hollywood and a local NBC affiliate. Hatch also did a radio interview.

FOB spokeswoman Traci Billingsley told Today that the agency could not reveal specific information about Hatch's situation.

Ribas said she hopes to get an explanation from officials on Wednesday.

Hatch, who is due to be released from house arrest Oct. 7, was convicted in 2006 of failing to pay taxes on the $1 million he won on the first season of Survivor. His case is currently being reviewed by a judge in Providence.
