With a few incidents of mail tampering occurring in recent months, the Ridgefield Police Department is offering some tips to help protect from becoming a victim of mail and package theft.  Homeowners should try not to leave letters and packages in the mailbox or at the door for any length of time.  Outgoing mail should be placed in a Blue Collection Box as close to the listed pick up time, of dropped off inside the local Post Office.  Ridgefield residents are urged to be careful about what is sent through the mail, and shouldn't risk sending cash.  If you do not receive a check, credit card, or other valuable mail you’re expecting, contact the sender as soon as possible and inquire about it.
