A 17-year-old carrying two knives was taken into custody after schools in Monticello, Iowa were locked down on Thursday.
A principal reported that two males dressed in black had walked past the school and one had a large knife in a sheath on his belt. All Monticello Community School District buildings were locked down as officers were sent to each.
An officer stationed at Central Middle School later saw two males matching the description. One was an adult who wasn't armed. The teenager with him was held pending charges for carrying dangerous weapons. Investigators have found no indication the teenager intended to pose a threat.
This comes after a 16-year-old student at Franklin Regional High School outside Pittsburgh went on a stabbing rampage Wednesday morning, wounding 21 classmates and a security guard.
Thursday afternoon, a 14-year-old boy and 20-year-old man were shot outside of Liberty Elementary School in Columbus, Ohio just before dismissal time. Neither have ties to the school. The boy is in critical condition, the man in stable condition. The school was locked down for about an hour.
