A Tacoma high school went on lockdown Monday after one shot was fired inside the boy's bathroom at Oakland Alternative High School.

Nobody was hit, according to Tacoma Police.

Police have identified a group of students who were involved in the incident from security footage and are going classroom to classroom to find the students. Two students were taken into custody.

A perimeter was set up around the high school while police issued a K-9 track.

Police previously reported the shot was fired outside the school at the lunchroom wall.

Over the weekend, two Tacoma students – a 12-year-old and a 15-year-old – were arrested for making online shooting threats to Truman Middle School and Lincoln High School, respectively.
