We report the radio continuum structure of the barred galaxy NGC 3367 with an angular resolution of ∼ 4 ′′ .5. The radio structure indicates emission from the disk and from a triple source consisting of the nucleus straddled by two extended sources (the lobes). The triple source shows an excess of radio continuum emission compared to the emission expected from the total radio-Hα correlation, suggesting a non-thermal origin probably related to AGN activity and not to star formation processes. The triple source is approximately 12 kpc in extent at a P.A. ≈ 40 • , close (but not aligned) to that of the stellar bar, P.A. ≈ 65 •. Only the southwest lobe is polarized. The polarization asymmetry between the two lobes suggests that the triple source axis is slightly out of the plane. If the origin of the emission is an outflow of plasma from an AGN, similar to weak radio galaxies and NGC 1068, NGC 3367 provides an excellent laboratory object to study a possible interaction of the ejected material and the barred galaxy.
