A former student at a Montgomery County high school is arrested in Towson after police say he made threats against current students.
Luis Cabrera is due in court Monday morning in Rockville.
Montgomery County police say Cabrera sent pictures to students at Walter Johnson High School in Bethesda.
In those pictures the 18-year-old is seen holding a loaded AR-15 rifle with the words "school shooter", "Ha,ha, I'm going to shoot up the school" and "I hate WJ" within the past month.
Another picture shows Cabrera holding a .40 caliber KelTek rifle.
Baltimore County Police assisted in arresting him Friday. He is being held without bond on one count of threat of mass violence.
