A Ridge man was arrested Tuesday in connection with the robbery of two Suffolk banks earlier this year, police said.

Christopher Collins, 25, of Ruth Lane, was charged with two counts of third-degree robbery in the Jan. 31 robbery of a Bank of America in East Setauket and a Capital One Bank in Nesconset on Feb. 17, police said. In both robberies, he passed a threatening note to a teller and no one was injured, police said.
