WEST LAFAYETTE, Ind. (AP) _ Campus police arrested four people who ran nude around a Purdue University quadrangle in the annual ''Nude Olympics.''

Two spectators in the estimated crowd of 1,000 at Cary Quadrangle also were arrested on suspicion of public intoxication and resisting law enforcement, police said.

The names of the four streakers, who were released after being arrested early Sunday on suspicion of public indecency, were not released, but Sgt. George Bittles said if any were students they would face disciplinary action from the university.

Purdue President Steven C. Beering banned the race in 1985, citing health hazards. Organizers try to stage it on the coldest night of the year.

Lafayette recorded an overnight low of 26 degrees.

The event, about 25 years old, has continued anually despite Beering's ban. In 1988, 10 men and a woman ran.
