The authorities at Louisiana State University are investigating whether fraternity hazing led to the death of a freshman on Thursday, the university said.

The student, Maxwell Raymond Gruver, 18, was taken from the Phi Delta Theta fraternity on Thursday morning to a hospital because of a “medical emergency” and was later pronounced dead, the university said in a statement. It did not elaborate on what happened to Mr. Gruver but said its Police Department was investigating the episode as a “potential hazing incident.”

“The death of Maxwell Gruver was tragic and untimely,” F. King Alexander, the university’s president, said in the statement. “There are allegations that Maxwell’s death was related to hazing, but I want to emphasize that this is an evolving situation.”

Mr. Alexander said that all fraternity and sorority activities at the school were suspended indefinitely. Recruitment at fraternities and sororities there ended last month.
