YONKERS: The city’s iconic blue mailboxes are headed for extinction after being long-time targets for thieves who fish out envelopes containing cash and checks using glue-covered bottles and rodent traps as bait.

But now the Yonkers mailbox theft has gotten more out of hand with thieves actually having keys to the mailboxes.

Police sources say the master keys were stolen in the Bronx

Repeated warnings have been issued for mailbox theft in the Bronx, Yonkers and other Westchester Communities along the Hudson River.

Later this year mailboxes in Yonkers are being retrofitted with mail slots only large enough for letters, meaning if you need to mail a padded envelope or a small package, you will need to make a trip to the post office.

The Yonkers mailboxes will also be retrofitted with new tamper proof locks.
