We prove that a non-trivial minimal blocking set with respect to hyperplanes in PG (r, 2), r≥ 3, is a skeleton contained in some s-flat with odd s≥ 3. We also consider non-trivial minimal blocking sets with respect to lines and planes in PG (r, 2), r≥ 3. Especially, we show that there are exactly two non-trivial minimal blocking sets with respect to lines and six non-trivial minimal blocking sets with respect to planes up to projective equivalence in PG (4, 2). A characterization of an elliptic quadric in PG (5, 2) as a special non-trivial minimal blocking set with respect to planes meeting every hyperplane in a non-trivial minimal blocking sets with respect to planes is also given.
