Manor High School was evacuated this morning, following reports of a suspicious device. The Austin Police Department's bomb squad has been dispatched to the scene to investigate.
The Travis County Sheriff's Office says Manor police found the device in a car, although it's uncertain whether the vehicle was parked on campus.
The Manor Police Department notes that students have been moved to Manor Middle School (12900 Gregg Manor Road). Parents are advised to stay away from the high school, as roads around the area have been blocked off.
We will have more details on the situation as it progresses.
