DALLAS (AP) - Police at Louisiana State University say they don't believe a suspect arrested in a campus bomb threat is connected to a similar call that led to an evacuation at the University of Texas at Austin last week.

LSU Police Capt. Corey Lalonde says 42-year-old William Bouvay Jr. of Baton Rouge was arrested late Tuesday night.

Lalonde said Wednesday investigators don't believe the phone threat was connected to threats made last week at UT and at campuses in North Dakota and Ohio. Searches on all campuses failed to turn up any explosives.

Lalonde says Bouvay was not an LSU student and investigators aren't sure on a motive.

Thousands evacuated the LSU campus on Monday after a similar scene played out in Austin three days earlier.
