Abstract
An Engel sink of an element of a group is a set such that for every all sufficiently long commutators belong to . (Thus, is an Engel element precisely when we can choose .) It is proved that if a profinite group admits an elementary abelian group of automorphisms of coprime order for a prime such that for each every element of the centralizer has a countable (or finite) Engel sink, then has a finite normal subgroup such that is locally nilpotent.
