As the school year draws to a close, an Arlington high school is the latest North Texas campus to be vandalized.
Arlington police said several people tripped an alarm inside of Lamar High School on West Lamar Boulevard at about 3 a.m. Friday, just hours before the final day of the school year was to begin.
A security guard confronted the group, who then dropped several paint cans while running away.
Paint was found in the school hallways and stairwells on the north end of the building, police said.
The school's principal, Dr. Larry Harmon, would not allow NBC 5 to film the graffiti Friday morning and referred all questions to district officials. However, an assistant principal told NBC 5 that the vandals were caught on video by surveillance cameras and that the graffiti, which was not vulgar in nature, should be cleaned up before the end of the school day.
Officials with the Arlington Independent School District said they are working with the Arlington Police Department to identify the group, believed to be students, so that they can be taken into custody.
Police have not yet said what charges the group may face.
Earlier this month, a stern warning was issued to students at Keller's Timber Creek High School after someone entered the school overnight and dumped items all around the building.
