Police have received three more reports of checks altered after they were stolen in mid-January from the outdoor deposit mailboxes outside Darien Post Office. More than $4,300 was stolen in these latest incidents. Police have received several other reports of checks being stolen after they were mailed from the same location. As they have in New York City, mailboxes have been replaced with a new type that is supposed to make it harder for thieves to “fish” from using strings and glue. Similar incidents have happened in other towns in the area and in the New York City metropolian region.
