Basing on IZMIRAN and NIRFI radio observations, we analyze an event which is characterized by sufficiently intense emission in the cm- and dm-ranges under almost total lack of metric bursts. This peculiarity appears to be caused by very slow speed (V~240 km/s) of a coronal mass ejection (CME) recorded in this event with SOHO/LASCO. Another consequence of the low speed of the CME was a so-called "CME cannibalism": in ~10 hours, at distance 25 Rs, this CME was overtaken and disturbed by another, fast halo-type CME.
