WATCH: Latest in arrests of Houston cheating scandal suspects
On Tuesday morning, federal prosecutors in Boston released nearly 300 pages of allegations in the operation dubbed "Varsity Blues."
At least two Houstonians were indicted in the scheme: Martin Fox, who is the president of a private tennis academy in Houston; and Niki Williams, an assistant teacher at a Houston high school and test administrator for the College Board and ACT.
Williams and Fox were taken into custody and later released on bond. Williams was released on a $20,000 unsecured bond, while Fox was freed on a $50,000 secured bond. Fox was also restricted travel outside of the Southern District of Texas other than court appearance in Massachusetts.
University of Texas men's tennis coach Michael Center has also been charged and placed on administrative leave. University of Texas Associate Athletics Director John Bianco released the following statement about the allegations:
"Federal authorities notified us this morning that we were victims of an organized criminal effort involving admissions. We have just become aware of charges against our Men's Tennis Coach Michael Center and he will be placed on administrative leave until further notice while we gather information. We are cooperating fully with the investigation. Integrity in admissions is vital to the academic and ethical standards of our university."

Two of the biggest celebrity names on the list are actresses Lori Loughlin and Felicity Huffman. Prosecutors alleged Huffman, Loughlin and 31 other parents from "wealth and privilege" paid a collective $25 million to get their children into colleges.
Prosecutors say this is the largest college admissions cheating scam ever prosecuted in the U.S. Those indicted allegedly paid bribes from $200,000 to up to $6 million each to get their children into the elite schools.
Prosecutors say the alleged scam was run by a college admissions counselor in California named William Singer who used testing centers in Houston and California.
"To facilitate the scam, Singer counseled parents to take their children to a therapist and get a letter saying that because of purported learning disabilities or other issues, the child needed additional time to complete the ACT or the SAT. Once the companies that administered those exams had agreed to the extra time, Singer arranged for the child to take the exam individually with one of the proctors he had bribed either at a location in Houston or at a location in California," said Andrew Lelling, U.S. attorney in Massachusetts.
The federal court documents are 269 pages in all.
No students were charged. In many cases, the students were not aware of the fraud, authorities said.
