FORT WORTH, Texas (AP) — Four Texas Christian University football players were among 17 students arrested Wednesday in a campus drug bust, police said.

Police said those arrested were caught making “hand-to-hand” sales of marijuana, cocaine, ecstasy and prescription drugs to undercover officers.

“There is no doubt,” TCU Police Chief Steve McGee said at a morning news conference following the arrests. He did not immediately identify the students.

McGee said the arrests came after a six-month investigation prompted by complaints from students, parents and others in the community. Police would not rule out more arrests, but said only people caught selling drugs had been arrested Wednesday.

School chancellor Victor Boschini called the students’ actions “simply unacceptable.”

Police said they had not determined whether any of the football players arrested were selling to other athletes. But Boschini suggested the four players’ involvement was not a sign of a larger issue.

“I don’t think it’s a football problem,” Boschini said.

A message seeking comment was left for TCU football spokesman Mark Cohen.

TCU is located in Fort Worth and has an enrollment of about 9,500 students. The Horned Frogs are set to join the Big 12 later this year in a move expected to be a boon for their athletic program.
