NAIROBI, Oct. 3 (Xinhua) -- University of Nairobi (UON) was Tuesday morning closed indefinitely following student unrest over last week's police assault that left 27 students with injuries.

The sudden closure of the institution came after the students blocked some roads, protesting last Thursday's invasion and assault by security officers who assaulted them in their campus hostels and lecture halls.

The University Senate announced the immediate closure citing deteriorating security situation at the main and other satellite campuses, ordering the students to vacate halls residence not later than 9.00 a.m..

"UON Senate has today closed the University with immediate effect due to the deteriorating security situation. Students have been asked to vacate the halls of residence with immediate effect but not later than 9.00 a.m.," the institution said.

There was tension at the institutions with plans of more protests Tuesday before the closure was announced. Anti-riot police were mobilized and placed at strategic locations to quell the riots.

The students had on Monday night gone on the rampage as they protested the invasion and assault by police last week. The protests forced motorists to seek alternative routes.

At least 27 students were Thursday injured when police invaded lecture halls and hostels and clobbered them to quell riots that were ongoing.

The police and independent oversight institutions are currently investigating the assault of the students by the police.

The students demanded that Vice-Chancellor Professor Peter Mbithi resign, accusing him of inviting the anti-riot police to invade their lecture halls and hostels to assault and steal from them.

The students blocked sections of the road on Monday night before police arrived to disperse them with gunshots that were fired to the air. They chanted "Mbithi must go! Mbithi must go!" with most unrest happening on the main campus.

The students burnt down security offices there, saying the officials had failed to stop the police invasion.
