There have been more than a dozen thefts from residential mail boxes over the last 10 weeks, according to police. Similar incidents are being investigated across the region, police said.
Police advise residents to avoid outgoing mail, especially checks, credit sensitive information or valuables within their mailbox for collection by the mail carrier until further notice.
Collection boxes and mailing directly from a U.S. Post Office facility are more secure options, police say.
Incidents of mail theft can be reported directly to the U.S. Postal Service at 203-625-3168.
Suspicious activity should be reported immediately to the Greenwich Police Department at 203-622-8001.
