The bright compact radio source PKS 1345 + 125 (4C 12.50) has been optically identified with a magnitude 17 galaxy with a redshift z = 0.122 and an unusual spectrum. Here, it is shown to be an elliptical galaxy with a compact radio source coincident with its optically undistinguished nucleus. An unresolved radio-quiet Seyfert nucleus with the same redshift as the elliptical galaxy is offset by 1.8 arc s from the radio source. The Seyfert nucleus is remarkable for its location in an elliptical galaxy, for its extreme far-infrared flux, and for the very low density in the broad-line region. A model of 1345 + 125 involving the dynamical merger of an elliptical galaxy with a spiral is presented. The merger has stripped the spiral galaxy of its interstellar gas, fuelling the nuclear engines in both galaxies, and allowing the broad-line region to stream out freely. The elliptical has acquired an envelope, and is becoming a radio-loud cD galaxy.
