IPOA has asked all University of Nairobi students who were assaulted by police to record statements at their office.
In a letter signed by CEO Joel Mabonga, the Independent Policing Oversight Authority said all affected students must visit their office at Upper Hill in Nairobi.
"It has come to our attention that the University of Nairobi has been indefinitely closed. IPOA is kindly appealing to the 26 students injured during the police assault on September28 not to leave until they have recorded statements with IPOA," read the Tuesday letter.
Mabonga noted this will help fast-track investigations.
He asked members of the public with information that would help the probe to get in touch with them.
"We urge patience and cooperation from all parties from whom we may require assistance to complete these investigations."
