ROCHESTER, N.Y. — Two University of Rochester students, one a current member of the football team and the other a former member, were rescued by a SWAT team a day after being abducted and held hostage, the police said on Monday.

The police provided no possible motive for the abduction, which ended Sunday night when the SWAT team entered a home about four miles from the university, where the two students were being held. Four people were taken into custody.

Both students, seniors from the Chicago area, were taken to a hospital, where one was recovering from a gunshot wound. The police said the student had been shot in the leg before they began their rescue operation. His injury was not life-threatening.

The two students, Nicholas Kollias, of Northbrook, Ill., and Ani Okeke Ewo, of Aurora, Ill., were reported missing on Saturday evening, hours after they were last seen near the school.
