A tip about drug sales led to the arrest of 39 year old Keith Gordon, who police say was living in Danbury and New Milford. Arrest warrants accuse him of selling cocaine from both homes. Police say searches turned up seven grams of cocaine, other pills, scales and packaging materials. Gordon also faces a charge of failing to register his Danbury address with the Deadly Weapon Offender Registry. He was released on bond and is due in Danbury Superior Court October 14.
