We use optical and radio data to examine the nature of active galactic nucleus (AGN) activity in these objects, and compare these with a carefully constructed control sample. We find that dust lane early-type galaxies are much more likely to host emission-line AGN than the control sample galaxies. Moreover, there is a strong correlation between radio and emission-line AGN activity in dust lane early-types, but not the control sample. Dust lane early-type galaxies show ","authors_text":"Chris Lintott, Edd Edmondson, Joseph Silk, Kevin Schawinski, Marc Sarzi, R. Mark Crockett, Stanislav S. Shabala, Steven P.
