We propose Chandra/ACIS-S observations to explore suggestions that at least some Blue Compact Dwarf Galaxies (BCDs) host AGN. Mrk 996 is an excellent test-case for this scenario. It has a unique set of observations, which allude to the presence of an AGN, yet many of its properties are typical of the overall BCD population. The detection of an AGN in Mrk 996 would demonstrate that black hole growth is taking place in low mass/metallicity BCDs, which are thought to be the local analogues of the first galaxies that formed in the early Universe out of near-primordial gas. This would offer a solution to the origin of seed black holes postulated by cosmological simulations in the early Universe to build the supermassive black holes at the centres of large spheroids.
