U.S. Postal Service inspectors were investigating a wave thefts from mailboxes in Bergen County, authorities said.
Anyone who believes their mailings have been compromised should contact either local police or the U.S. Postal Inspection Service: (877) 876-2455 .
The tampered-with boxes included one in Glen Rock at De Boer Drive and Harristown Road, borough Police Chief Dean Ackermann said.
In recent years, the service has retrofitted postal boxes to thwart thieves who "fish" for mail by rigging adhesive tape or other devices into the opening and then pulling out envelopes to search for checks or cash.
