We show that ifis a (not necessarily unital) separable, simple and non-type I C-algebra, then for every properly infinite hyperfinite von Neumann algebrawith separable predual, its Ocneanu central sequence algebraarises as a sub-quotient of the central sequence algebradefined by the second-named author. In particular, this answers affirmatively the question of Kirchberg [‘Central sequences in C-algebras and strongly purely infinite algebras’,Operator algebras: the Abel Symposium 2004, Proceedings of the First Abel Symposium, Oslo, 3–5 September 2004 (eds O. Bratteli, S. Neshveyev and C. Skau; Springer, Berlin, Heidelberg, 2006), X, 279, 175–231]: the central sequence C-algebra of the reduced free group C-algebrais non-commutative.
