(CNN) -- A member of the group dubbed the "Jena 6" is facing misdemeanor assault charges after a fight at his Texas high school Wednesday, police said Thursday.

Bryant Purvis, 19, was arrested after the incident at Hebron High School in Carrollton, Texas. Carrollton police Sgt. John Singleton told CNN the altercation does not appear to be racially motivated.

School officials contacted police about the fight Wednesday morning. An 18-year-old student told authorities two males approached him and asked if he had flattened the tires of "their homeboy's" car, according to an affidavit supporting the arrest warrant.

The student said he didn't, but the two told him they didn't believe him and walked away.

Purvis, he said, approached him from behind immediately afterward, then grabbed him with one hand and began to choke him.

"Purvis continued to choke [the student] and told him, 'Don't you ever mess with my car again,'" the affidavit said. "Purvis then pushed his head into the seating area of the bench," causing the student to strike his left eye, then walked away.

The affidavit said that in a written statement, Purvis wrote, "I walked over to him and grabbed him by his neck, then told him not to mess with my car anymore, then I left."

Police reported the student had marks on his neck and bruising on his eye.
