9:45 a.m.

Police say they've arrested a suspect in the first on-campus killing at the University of Texas in five decades.

The Austin Police Department said via Twitter on Friday that a suspect is in custody and more details will come during a press briefing later.

The body of 18-year-old Haruka Weiser, a dance major from Portland, Oregon, was discovered Tuesday in a creek near the alumni center and football stadium in the heart of campus.

Police have released surveillance video of a man they say is a suspect walking a bike around 11 p.m. Sunday near to where her body was found.

Campus President Greg Fenves has said the "unthinkable brutality against Haruka is an attack on our entire family."

Austin Police Chief Art Avedevo says he's confident a man who appears on University of Texas surveillance video killed a first-year dance student whose body was found on campus.

Acevedo told ABC's "Good Morning America" on Friday that the location and timing of the man's appearance on campus, according to the video, indicate he is responsible for the slaying of 18-year-old Haruka Weiser.

Weiser, from Portland, Oregon, was last seen Sunday night leaving the school's drama building. Her body was found in a creek on Tuesday.

The video appears to show a man pushing a red or pink bicycle near the school's football stadium, which is near the creek, around the time that Weiser was last seen.

Austin police are hunting for a suspect spotted on University of Texas surveillance video around the time that a first-year dance student was killed on campus.

The body of 18-year-old Haruka Weiser was found in a creek Tuesday. Police say Weiser was last seen Sunday night leaving UT's drama building.

Authorities haven't revealed details of how she died, but UT President Greg Fenves has described her killing as "horrifying and incomprehensible."

Police say the man appears on surveillance video pushing a red or pink bicycle north of the stadium, which is near the creek, around 11 p.m. Sunday. Assistant Austin Police Chief Troy Gay says it's unclear if he is a student, but that he was in the area for a couple of hours. No weapon has been recovered.
