Wilton Police are investigating a break in of a mail box at the post office. Forced entry was made into United States Postal Service Collection Box overnight Saturday into Sunday. Similar activity was also reported in the Town of Weston. Wilton Police say stealing mail from a residential mailbox or a public collection box continues to trend. Police are advising residents that if anything valuable is being mailed, including personal checks, to use a mail slot inside the Post Office building to avoid being a victim. Anyone who recently used a collection box at the Wilton Post Office over the weekend is asked to monitor accounts and report fraudulent activity for investigation.
