One person was detained at Case Western Reserve University Friday night after students received a text alert about an armed person in a dormitory on the South Side campus.

Just before 8 p.m., a crash occurred near Cedar Road in Cleveland Heights, and four armed juveniles fled the scene on foot, according to Case Western Police.
Around 8:18 p.m., one of the juveniles was seen entering Michelson House by "piggybacking" a student who had swiped into the residence hall, prompting the shelter-in-place order, CWRU Police said.
Case Western Police and Cleveland Heights Police located the juvenile in a janitor's closet and detained him, police said.
Police searched and cleared the Michelson, Kusch and Glazer houses, and the university gave an update on the situation through a post on X:
CWRU Alert (9:58 p.m.): CWRU Alert: After investigating, manually checking and clearing buildings, and viewing security camera and drone footage, CWRU police have issued an all clear for campus. Normal activities can resume, but individuals should use caution.
