Police found drugs, guns and a big stash of money when they busted a 20-year-old who they say ran a high-level drug business out of his parent?s Lewisboro mansion.

The Westchester Narcotics Unit in conjunction with Bedford police arrested Christopher Bua Thursday after a four-month investigation of drug trafficking. At Bua?s parent?s house the police found 1 kilo of cocaine, a handgun, an assault rifle, drug paraphernalia and $75,000 in cash. Police also found drugs and cash belonging to Bua in an apartment in Connecticut.

Police say residents in the town alerted them to Bua?s activities. Bua is charged with felony drug possession and firearm possession. His parents have not been charged.
