Md. teen arrested for making threats to 'shoot up' Montgomery County high school

BETHESDA, Md. - An 18-year-old former Walter Johnson High School student has been arrested, police say, for making threats against students at the school.

Montgomery County police say Luis Amilcar Cabrera of the 200 block of Congressional Lane in Rockville was arrested in Towson, Maryland, with the help of Baltimore County police.

According to police, several students at Walter Johnson in Bethesda notified their School Resource Officer after seeing photographs and a threatening statement by Cabrera on the social media app Snapchat.

According to the investigators, Cabrera was seen in a photo holding an AR-15 rifle with loaded magazines which included the words, "School shooter."

The reporting students stated that Cabrera has also stated that he has posted, "I hate WJ" and "Ha, ha, I'm going to shoot up the school," within the past month.

They say Cabrera has stated in videos that he owns the AR-15 and keeps it with him at all times for protection. He is also seen holding a .40 caliber KelTek rifle.

Officials say Cabrera was charged on Friday with one count of threat of mass violence. He is currently being held without bond
