Officials are investigating who was responsible for bomb threats Friday that evacuated North Dakota State University in Fargo and the University of Texas in Austin.
FBI spokesman Kyle Loven said officials are trying to determine whether the threats were linked. A phone call to NDSU around 9 a.m. Friday warned of a bomb on campus, and a similar call was placed to the University of Texas at Austin at 8:35 a.m., Loven said.
"It is a little too early to determine if there was a connection," Loven said. "We will follow any investigative leads."
No bombs surfaced at either campus, authorities said. By 2 p.m., NDSU resumed classes. Texas reopened its buildings at noon.
No other Fargo area schools, or schools in Minnesota, received similar threats. Many, however, were on alert.
"NDSU is requiring all employees and students to leave campus by 10:15 a.m.," the initial alert from campus police read. "This includes residence hall students, who, if necessary, should walk to locations off campus."The alert added that the evacuation also covered the school's downtown buildings and agricultural facilities. NDSU President Dean Bresciani said about 20,000 people, 14,000 of them students and the rest employees, were covered by the evacuation.
The alert gave no details about the bomb threat, adding that more information would be released later.
This is the third bomb threat in eastern North Dakota this week. One closed access to Fargo's Hector International Airport in Fargo, and the other was reported at the Grand Forks airport.
