STAMFORD — A Darien man has been arrested after police say he sold crack cocaine to an undercover officer several times.

Frank Green, 34, of Allen O’Neill Drive, has been charged with three counts each of sale of narcotics and conspiracy to sell narcotics.

Capt. Richard Conklin said the Stamford police department’s Narcotics and Organized Crime squad led the investigation with the help of the Darien Police Department.

Conklin said Green sold medium-sized amounts of cocaine to the undercover officer on three occasions in downtown Stamford.

Conklin said officers seized more than $2,600 in Green’s possession when he was arrested on Thursday. Police also took his Dodge Challenger.

Green, a former Stamford resident, was released after posting a $150,000 court appearance bond.
