Matthew Samatoski was arrested and charged with illegal possession of narcotics.
On Thursday, undercover detectives saw Samatoski "make a hand-to-hand drug transaction" at the Riverwalk on Canal Street, police said. He was stopped by detectives and found to be in possession of cocaine, police said.
"The arrest stems from a continuing downtown surveillance operation where undercover detectives are vigilantly patrolling the area for illegal drug activity," Detective Richard Bango said in a statement.
He was released for an appearance in Derby Superior Court on May 14.
"Shelton undercover detectives will continue to monitor the downtown area for illegal activity, and patrol units will continue to make a presence in the area," Bango said.
