Recent mail thefts in Fairfield are prompting police to warn people about where they send their mail from, especially ones that include checks.

"The postal office has created these new blue boxes that were supposed to be a little bit harder to target and they found a way around it," said Fairfield Police Lt. Edward Nook.

Fairfield Police say they arrested these four men from New York over the weekend for stealing mail from blue postal drop-off boxes.

Police say they got a tip early Friday morning about suspicious activity in Southport.

"When the officers showed up, they saw someone sleeping with the engine running which kind of prompted their inquiry," said Nook.

Police say the suspects used a belt that they put an adhesive on from rat traps to steal the mail.

"Whatever sticks, they just fish it out," said Nook.

Police say there were a couple of foot pursuits, including one near the Ukrainian Club where police made two arrests.

Officials say one of the suspects incriminated himself.

"When he was scrolling through his phone to show a picture of his passport the officers were able to observe pictures of checks and then in the vehicle, they also saw miscellaneous mail and some checks," said Nook.

Police recommend people do not mail checks from their home mailboxes or blue postal boxes, but at the post office.

Officials say a postal inspector assisted in the investigation.
