Four missing Moi University students are feared to have joined terror group al Shabaab.
The number of students from the university, suspected to have joined the al Qaeda-linked group, has risen to eight since November 2015.
Uasin Gishu county commissioner Abdi Hassan said on Saturday that some parents are being investigated for helping their children to join the terror group.
It emerged in June last year that some University of Nairobi students are and al Shabaab.
The head of the National Counter Terrorism Centre said
he had evidence some students in Nairobi and elsewhere
were on the payroll of the two terror groups.
Director Isaac Ochieng
addressed a forum on countering violent extremism hosted by the UoN and the Interior ministry at the university's Taifa Hall.
He neither elaborated on the evidence nor said how many students were estimated to be on terror payrolls.
