University of Texas police and Harris County sheriff's deputies have arrested a 23-year-old Houston-area man who they say threatened to shoot at least 200 people at the school in Austin.
Authorities say Sean Evan Haddon has been charged with making a terrorist threat.
He's in the Harris County jail following his arrest Sunday morning.
Police say phone calls began April 7 with a bomb threat to their campus police headquarters. Another similar call was received Thursday, followed by a call Friday to the university's Human Resource Service Center threatening to shoot "at least 200 people." That call was tracked to Haddon's home in Crosby, a northeast Houston suburb about 160 miles east of Austin.
Police say after each call officers found nothing suspicious to merit a campus-wide alert.
