TRAVIS COUNTY -- Due to a potential safety threat at Westlake High School, the campus will be on lockdown Friday.
A threat was made against the school and staff Thursday.
All of the doors into Westlake High were locked until 8 a.m. Friday, at which time students were allowed inside to prepare for the start of school at 8:40 a.m.
The superintendent and principal sent a letter home to parents. It did not say exactly what type of threat was made, but it did state that there have been similar situations at schools around the state lately.
"We had a student notify a Westlake administrator yesterday that he saw some graffiti in a bathroom stall. It was enough of a concern where we wanted to make sure that parents were alerted," said Eanes ISD spokesperson Claudia McWhorter Friday.
Police officers started patrols at the school Thursday night and will continue to keep a close eye on the school Friday.
There will also be more adults on campus to help keep students safe.
Students who are members of the band or athletes who needed to access the school before 8 a.m. were allowed in through monitored doors.
Every classroom and area of the campus was searched, according to school officials. Nothing unusual was found. The school will operate as normal, except for the increased security.
Friday Principal John Carter sent another update to parents that said in part, "Providing a safe environment for students is always a priority. We have heard from some of you who have concerns about the situation. Please know that we are doing everything we can to ensure the safety of our students and staff and that we are following our emergency plans, working with law enforcement, and staying vigilant."
