Violence over a cricket match

What happened in Jahangirnagar University (JU) on February 19 is appalling. Students of JU were allegedly attacked by locals over a cricket match.

While the police were eventually able to get the situation under control, there have been no cases filed and it seems nothing is going to be done about it. Will this indiscriminate violence against students have no consequences? Or was there a motive bigger than just a dispute over a cricket match?
