Police Turns NANS Protest Bloody

A peaceful protest organized by Nigeria Students in Delta State over the continuous Academic Staff Union of Universities (ASUU) strike turned out to be bloody as police were alleged to have fired both tear gas and gunshots at students to prevent them from protesting. 
Consequently many of the students were alleged to have received various degree of injuries.
A 300level student who was allegedly seriously injured is presently receiving treatment in an hospital.
But what we are yet to understand here is the crime the students has committed.
