Police, FBI investigating threat against Towson High School

Police are expanding an investigation into a social media post that threatened to harm Towson High School students. Baltimore County police told 11 News investigators are working with the FBI to find out if the threat was made outside of Maryland, or even outside the country. The first social media threat showed up Thursday specifically targeting Towson High School for something to take place Friday. Whoever made the threat said they would pull out a small rifle from their backpack and kill students. Since then, county police have increased officers' presence on campus both on the perimeters and inside the school building.
