WEST HARTFORD, Conn. (WTNH) — The West Hartford Police Department is warning about “check washing” scams.

These con artists apparently change the payee names and often the dollar amounts on checks. Then fraudulently deposit them. Usually, they are stolen from mailboxes and literally washed in chemicals to clear the ink.

Police say you can protect your money by dropping off mail before the last pickup or go right to your post office.
