(Updated at 9:50 a.m.) Seven recent Wakefield High School (4901 S. Chesterfield Road) graduates were arrested at the school around 5:15 this morning.

Police were called after a security guard spotted individuals on the roof. During their investigation, police found that the four adults and three juveniles had climbed onto the roof via a pole on the outside of the school, and proceeded to drink beer on the roof.

The former students, who graduated on Wednesday, June 20, tried to flee the scene. One of the subjects attempted to resist arrest and engaged in a physical altercation with an officer. He was transported to the hospital with minor injuries, but has since been released back into police custody for questioning.

According to police spokesman Dustin Sternbeck, this incident has similarities to one last week on the second floor of the school, which resulted in vandalism.  K9 units were brought in to investigate today’s incident, but no vandalism was discovered. The former students are in custody speaking with detectives to see if they have information about last week’s incident. However, Arlington Public Schools spokesman Frank Bellavia says there was no vandalism last week, somebody simply set off a fire extinguisher.

“It’s just a poor decision on their behalf, to bring alcohol onto the school property and drink,” Sternbeck said. “They weren’t here to vandalize the property, they were just here to have a good time, but it was a poor decision making process.”

All the subjects will be charged with trespassing, and the adults will be charged with contributing to the delinquency of a minor.

“It’s an unfortunate incident,” said Bellavia. “They made a poor decision.”

It’s unclear if there will be any sort of punishment issued by APS. Bellavia said system officials will have to look into the incident, because the subjects are no longer students.
