Brothers Rocky and Leon Houston have been arrested. They are being held at the Knox County Jail on a hold for U.S. Marshals, according to the jail's website.
The brothers were booked into the jail on Saturday. John Sanchez, a spokesman for the U.S. Marshals Service, said he wasn't at liberty to discuss the reason for their arrest.
"I will have to wait until I am briefed and that's not going to happen for a while," Sanchez said.
