A graduation ceremony for nursing students at Howard University's College of Nursing and Allied Health Sciences ended abruptly and in chaos after angry family members chanted “Let us in!” and pounded on the doors and smashed a window after being locked out when Cramton Auditorium hit capacity. 

School officials told students and their families mid-ceremony that the fire department had come to shut things down. However, D.C. Fire and EMS denied shutting down the graduation.
