Two Columbia schools and the East Columbia library briefly were placed under a modified lockdown Wednesday after a school resource officer prevented a possible juvenile altercation in front of Lake Elkhorn Middle School, according to Howard County Police.
Police said at approximately 3 p.m. the officer found three juveniles about to engage in an altercation, and called for backup.
Lake Elkhorn Middle School and Cradlerock Elementary School, along with the library, were placed under modified lockdown because of the incident.
The three juveniles, who were not students, were arrested. Two juveniles, ages 12 and 13 respectively, were charged with trespassing, while a 14-year-old was charged with disorderly conduct, police said.
Police said it is unknown what the altercation was about.
According to an email to parents signed by both Lake Elkhorn Middle School and Cradlerock Elementary School principals, the schools were placed under modified lockdown to "ensure no trespassers could enter our facilities and to keep the staff and students inside."
The principals emphasized no one was injured in connection with the incident.
The modified lockdown was lifted less than an hour after it was imposed.
