The Hollywood Hills Burglar Bunch may have been far more dangerous than first thought -- cops say one of the suspected members had built a serious arsenal of hardcore drugs, guns and ammunition.
Cops recently executed a search warrant on the L.A. home of Johnny "Dangerous" Ajar -- and what they found caused authorities to charge the 27-year-old with 10 felonies including:
-- Six counts possession for sale of a controlled substance ... cocaine, oxycodone, psilocybin (aka mushrooms), Ecstasy, Clonazepam (an anxiety pill), Alprazolam (aka Xanax).
-- Three counts possession of a firearm by a felon for two Sig Sauer 9MM handguns and a Remington shotgun.
-- One count possession of ammunition.
As we first reported, Ajar was convicted of trying to sell 500 grams of cocaine back in 2002 -- and spent over a year-and-a-half in a Wyoming prison.
Now, authorities say he's on the run and considered armed and dangerous.
