fire incident at UNILAG

An early morning fire on Tuesday gutted some offices in the Physics Department of the Faculty of Science building at the University of Lagos, Akoka, Lagos State.
The fire appeared to have broken out from the second floor of the three-storey building, causing panic in the school.
It took the combined effort of firemen from the Federal Fire Service, Lagos State Fire Service, Yaba College of Technology and UNILAG as well as staff and students of the institution to put out the fire.
What really is the cause of this incident, we heard that of Ajyai Crowther about a student's death and the students had to burn down a faculty of the school.What then is the reason for this fire gut at UNILAG.
