Abstract
Let be KLT threefold singularity over an algebraically closed field of positive characteristic . We prove that its local \'etale fundamental group is tame and finite. Further, we show that every finite unipotent torsor over a big open of is realized as the restriction of a finite unipotent torsor over .
