STAMFORD - Federal prosecutors say a judge has sentenced a crack dealer from Stamford to 20 years in prison.

Federal authorities say Okeiba Sadio, 31, traveled from Stamford to the Bronx 11 times in 2009 to buy crack cocaine, which he then sold.

Prosecutors say Sadio is among 52 people who've been charged with drug offenses as a result of an investigation known as "Operation Big Loot."
