A 15-year-old faces a weapon charge after he brought a gun to a Gwinnett County school, district officials said.

The student was arrested after Lanier High School administrators got a tip he had a gun on campus, Principal Christopher Martin said in a statement.

“We moved quickly to investigate and during our search we did find that a student had a gun in his possession,” Martin said.

In addition to criminal charges, the student also faces school disciplinary action. His name was not released because he is a juvenile.

The discovery comes just a day after 17 people were killed at a South Florida school by alleged shooter Nikolas Cruz. Authorities say Cruz, 19, legally purchased an AR-15 rifle and shot students and staff at Marjory Stoneman Douglas High School in Parkland, Fla. Cruz had been expelled from the school.

The deadly shooting prompted metro Atlanta high schools, including Lanier High School, to have increased security.

“News of a weapon on campus is unsettling for us all, especially in light of the tragic events from yesterday in Florida,” Martin said. “As you all know, we have security measures in place at our school. However, we can never underestimate the role we all ... play in keeping our school safe.”
