About nine people, including an assistant proctor of the Chattogram University, were injured on Friday night in a clash between two groups of the CU unit of the Bangladesh Chhatra League.
The clash broke out at 11pm in front of the Suhrawardy Hall between two BCL groups: Sixty Nine and VX.
Due to previous hostility, the leaders and activists of both groups were chanting provocative slogans against each other.
Later, they locked in repeated clashes.
They brandished locally-made weapons and pelted brick chips at each other.
The nine injured were Assistant Proctor Shahidul Islam and eight BCL men in the two-hour long fight.
