Thursday update: The university president, Gary Ransdell, said that five students questioned in connection with the fights had been released. The police on the campus still had no evidence to substantiate that shots had been fired, adding that the five students denied involvement and no weapons were found in their possession.

The Western Kentucky University campus in Bowling Green was on lockdown Wednesday afternoon after reports that shots were fired on campus.

But more than two hours after the alleged incident, police were unable to confirm that any shooting had occurred. University police said only that they had confirmed that a physical fight between two groups of individuals had taken place near the Pearce-Ford Tower dormitory on the main campus.
