The analysis of the researched scientific problems on counteraction to crimes, committed by organized groups and criminal organizations, which are formed on an ethnic basis, now necessitates further research of ethnic crime in Ukraine and the world in general.

Thus, for the effective interaction of law enforcement agencies in combating crimes, committed by organized groups and criminal organizations that are formed on an ethnic basis, a sound concept of such cooperation is needed, which is currently lacking.

An author's definition of the concept of interaction among police during counteraction to crimes, committed by organized groups and criminal organizations, formed on ethnic basi, is given
