Greenwich Police announced on Thursday that a blue drop off mailbox at the Old Greenwich Post Office was found damaged, and that a second mailbox was found tampered with in Cos Cob.
Lt Slusarz said it was unknown whether any mail has been taken, but the US Postal Service is handling the investigation.
Residents and businesses who may have used a mail drop-off box in Old Greenwich or Cos Cob should follow-up with the recipients of their mail to confirm receipt.
Further steps should be taken to protect any sensitive information in the out-going mail and monitor banks accounts.
