AUSTIN (KXAN) — Lockouts have been lifted and normal operations have resumed at a middle school and high school in northwest Austin Friday after receiving anonymous bomb threats, according to the school district.

Leander ISD said that the two schools — Vandegrift High School at 9500 McNeil Dr. and Four Points Middle School at 9700 McNeil Dr. — were placed on lockout at 12:15 p.m. During a lockout, the school day proceeds as normal but without any activities outside.

The school district said the lockout at Vandergrift High School was lifted at 1:30 p.m. The school has resumed classes and they are operating on an adjusted schedule.

The lockout at Four Points Middle School was lifted at 1:45 p.m. and students have also resumed classes on an adjusted schedule.

The lockouts were caused by an anonymous bomb threat. According to APD, they responded to an assist non-emergency call 9500 block of McNeil Drive at 12:07 p.m. Students were held in their classrooms during the search.

APD says no suspicious items were located during a search at either school.
