Recently, a substantial population of Blazar-like sources exhibiting sharp near-infrared cutoffs and hence exceedingly reddened optical to near-infrared colours (Bj – K ≿ 6) have been discovered in a complete sample of flat spectrum radio sources (Drinkwater et al. 1996). We argue that such “red” colours cannot be due to a synchrotron radiation mechanism alone.
