NEW CANAAN — An early morning traffic stop Friday led to the arrest of two Bridgeport men for allegedly stealing mail from residential mailboxes in New Canaan.

Shortly before 12:15 a.m. Friday an officer stopped a vehicle driven by Jeffrey A. Nunez, 36, after officers said it crossed the white fog line on Cherry Street.

Police said that while speaking with Nunez, “the officer observed a black plastic bag within the vehicle that contained multiple pieces of mail.”

The mail was found to be from residences on Frogtown Road in New Canaan and did not belong to Nunez or the other two occupants of the car.

Nunez was charged with fifth-degree larceny and conspiracy to commit fifth-degree larceny. His bond was $600 for court Oct. 26.

Leon Luis Daniel Blandin, 19, of Bridgeport, was arrested on both those charges, as well as interfering with an officer for allegedly giving a false name. He was held on a $5,000 bond and taken to state Superior Court in Stamford Friday morning.

A 26-year-old Port Chester, N.Y., woman who was in the front passenger’s seat was issued a ticket for possession of marijuana.

New Canaan Police have six open cases for theft of mail from residential mailboxes, some resulting in check washing, which is altering a check to make it payable to an unauthorized person.

Thefts were reported Thursday on Valley Road and Huckleberry Hill Road, as well as in neighboring towns, New Canaan Police Chief Leon Krolikowski said.

Police said it is not known if those charged Friday are tied to any of the other thefts in town.

Krolikowski encouraged residents to take outgoing mail to the Post Office rather than leave it in a mailbox, and to sign up for the Postal Services Informed Delivery program at informeddelivery.usps.com.

Police also advised residents not to leave mail that has been delivered in mailboxes overnight.
