Kirinyaga University College students Tuesday went on the rampage demanding the removal of their registrar Mr Phineas Munyi.
The students boycotted studies and walked out of the College in protest.
They then barricaded the usually busy Kerugoya-Kutus road paralysing transport for the better part of the morning.
They said Mr Munyi had overstayed in the college and he should therefore go.
The students also want the College principal who was transferred be brought back unconditionally.
They harassed motorists plying the route for hours, causing tension in the area.
But police moved in and engaged them in running battles.
The officers hurled tear gas canisters at the hostile students who responded by throwing stones.
The students were overpowered and forced back to the College where they chased away workers.
Police later removed the barricades on the road and kept guard.
At around 11.30am, the students raided the kitchen and flushed out the cooks.
