Derail Jarvis Green, 23, was booked into the Denton County jail on Tuesday and released after posting $12,500 bond. He faces charges of engaging in organized criminal activity and drug possession.

Green is the third person associated with the team arrested as a result of the investigation, after former teammate Rickey Lynn Brice Jr. and former student manager Brian Emmerson Johnson.

A fourth man — 39-year-old Marlon Andre Terry — was arrested Thursday on a charge of prostitution.

Terry, who resigned last week as assistant basketball coach at Nicholls State University in Thibodaux, La., was released from the Denton County jail after posting $500 bond.

University police started investigating in late March after officials received a report of a sexual assault that involved prostitution off-campus.

The residence-hall assistant who made the report told campus police that he was with one of the victims when she received a call from Johnson and Green, police records indicate. During the call, the two men solicited the victim to engage in prostitution, according to an arrest-warrant affidavit.

UNT police interviewed Johnson on April 25, and he admitted to having the conversation and making other arrangements for clients to engage in sexual acts in exchange for money, according to police. Cellphone records confirmed that Johnson had arranged for Terry to meet with a second victim on March 29, the affidavit says.

The second victim said Terry took her to an off-campus location in Denton where she performed sex acts for money, the affidavit says.

Johnson, 29, was arrested May 3 and booked into the Denton County jail on charges of engaging in organized criminal activity and marijuana possession. He was released after posting $3,500 bond.

It's not clear whether the two victims are students.

While officials searched Johnson's home, they found marijuana. His roommate, Brice, was arrested on a charge of marijuana possession.

Brice, 20, was booked into the Denton County jail May 1 and released after posting $1,000 bond.

The university said in a statement that the case "appears to be an isolated incident involving individuals who are no longer associated with our men's basketball program." Brice left the team in April, and Green is not listed on the roster.

The university said it had hired a law firm to conduct an independent review of the situation.

UNT Athletics Director Wren Baker said in a prepared statement that "even one incident of misconduct is one too many."

Basketball coach Grant "McCasland and I are committed to building a championship culture on and off the court and will not tolerate anything less than a safe, respectful and welcoming environment where all of our students can learn, grow, and thrive," Baker said.

UNT President Neal Smatresk said in a statement that the allegations are contrary to the university's values and its student code of conduct.

"The university is cooperating fully with investigators and working diligently to obtain all facts pertaining to this issue," Smatresk said. "We will be as transparent as possible with the university community."

Last year, a student filed a federal civil-rights lawsuit against UNT, alleging that the school failed to properly investigate after she was sexually assaulted by a university employee. In September, the U.S. Department of Education opened a Title IX investigation of UNT.
