The Ridgefield Police Department has recently received reports of mail tampering.  Police are offering tips to help protect against mail and package theft.  Residents are encouraged to not leave letters and packages in the mailbox or at the door for any length of time.  Mail should be dropped in blue collection boxes close to pick up time.  Anyone who doesn't receive an expected check, credit card, or other valuable mail should contact the sender as soon as possible and inquire about it.
