Three intruders entered a dormitory at Guilford College this weekend in search of football players involved in a fight with Palestinian students, but fled when police were called, authorities said.

No arrests were immediately made, police Lt. James Hinson said.

"Threats were made," he said. "But who the threats were directed against and who made them, we can't comment on that."

The people from off-campus entered Bryan Hall shortly after noon Sunday, "looking for football players" involved in the Jan. 20 fight at the dormitory, college spokesman Ty Buckner said.

All the students involved in the altercation have moved off campus. It wasn't immediately clear whether any of the three gained access to the players' unoccupied rooms, Buckner said.

A Guilford officer and city police responded to calls reporting the intrusion, and the group left. Another campus police officer saw them a short time later, still on campus, and followed their car as they left, Buckner said.

That officer was able to get a "detailed description of the individuals and the car that they were driving," according to a statement from the college.

The college has put extra security at Bryan Hall and asked city police to add patrols in the area, the statement said.

A magistrate judge has charged six Guilford football players with misdemeanor assault and five of them with ethnic intimidation based on complaints filed by three Palestinian students after the fight early Jan. 20.

The Palestinian students, one of whom was visiting from North Carolina State University in Raleigh, said as many as 15 players beat them with fists, feet and brass knuckles while calling them "terrorists" and using ethnic slurs, according to court documents.

The father of one of the players insists that the Palestinian students started the fight.
