We propose destructive stellar collisions in the Broad Lines Regions (BLR) of Active Galactic Nuclei (AGN) as an effective mechanism of copious production of very high energy cosmic rays. For some rather short stage of AGN evolution the total rate of energy generation by stellar collisions can exceed the Eddington luminosity. We have evaluated the parameters of AGN's under conditions of effective energy generation. In the proposed model the cosmic rays are accelerated by supernova-like expanding shocks produced by the destruction of a great number of stars. The gamma-ray luminosities of AGN due to such a mechanism are estimated. Sources of this type can be detected by experiments EGRET on GRO and Cherenkov telescopes. The strong source of gamma-rays recently identified with the quasar 3C 279 by EGRET team is proposed as the possible candidate to our model.
