We present {\it Gemini} longslit optical spectroscopy and VLA radioobservations of the nuclear region of NGC 4178, a late-type bulgeless diskgalaxy recently confirmed to host an AGN through infrared and X-rayobservations. Our observations reveal that the dynamical center of the galaxyis coincident with the location of the {\it Chandra} X-ray point sourcediscovered in a previous work, providing further support for the presence of anAGN. While the X-ray and IR observations provide robust evidence for an AGN,the optical spectrum shows no evidence for the AGN, underscoring the need forthe penetrative power of mid-IR and X-ray observations in finding buried orweak AGNs in this class of galaxy. Finally, the upper limit to the radio flux,together with our previous X-ray and IR results, is consistent with thescenario in which NGC 4178 harbors a deeply buried AGN accreting at a highrate.
