Massive black holes in stripped nuclei with masses above 107 solar mass in the Virgo and Fornax clusters have been discovered, but so far the expected population of black holes have not been found in the more abundant stripped nuclei expected at lower masses. The Local Group's most massive clusters are the perfect place to hunt for the intermediate mass black holes (IMBHs). IMBHs, mainly cannot be detected robustly as they also imitate the presence of a collection of stellar mass black holes. These measurements are needed because they are a very important link in understanding the formation mechanisms of black hole progenitors and formation of black holes in low-mass clusters.
