Sam Bankman-Fried might see his bail conditions tighten.

Last Friday U.S. prosecutors expressed concerns to the court that the former FTX CEO could be attempting to influence witnesses in the fraud case against him. They cited a Signal message Bankman-Fried sent to the FTX US general counsel on January 15, in which he stated: “I would really love to reconnect and see if there’s a way for us to have a constructive relationship, use each other as resources when possible, or at least vet things with each other.”

According to prosecutors, Bankman-Fried’s attempt at reaching out to the general counsel—who may have damaging information about him—was “suggestive of an effort to influence [their] potential testimony.” Even if it wasn’t the case, they said, his contact could intimidate the witness into not coming forward or testifying. They also pointed to Bankman-Fried using Signal (an encrypted messaging app that gives users the ability to auto-delete their messages) to communicate as a source of concern.

Prosecutors therefore asked for the court to ban Bankman-Fried from communicating with current or former FTX and Alameda Research employees without a lawyer being present. Exempt from the condition were his family members: his father, Joseph Bankman, his mother, Barbara Fried, and his brother, Gabriel Bankman-Fried.
