Two Danbury women have been arrested on a number of drug related offenses.  Police received neighbor complaints about illegal sales weeks ago and police launched an investigation into 56-year old Barbara Fleckenstein and 33-year old Erin Melissa Rusek.  On Wednesday afternoon, officers set up surveillance outside their Lake Breeze Drive home.  They were stopped after attempting to drive away.  Police found  a substantial quantity of crack cocaine, powder cocaine, heroin and money.  The pair was also in possession of a scale and packaging material.  Rusek, who is nine months pregnant, and Fleckenstein were each charged with 3 counts of possession and possession with intent to sell and one count of possession of drug paraphernalia.  Both were released on bond.
