Charles Walls is warning his fellow Bed-Stuy neighbors about potential mail theft in their neighborhood.

He tells News 12 he discovered 10 opened cards in his mailbox last week.

“Multiple different cards letters, that were all opened like they’ve been searched and money taken out," said Walls.

Walls says he hasn't opened his mailbox in nearly two months.

“I have auto pay and usually already know the mail that is going to come in," said Walls.

Each card was addressed to a different stranger in the neighborhood.

“All personal, nothing from a bank or from a utility bill, so I can assume why the culprit would want to target these," said Walls.

He says the only people who have access to his mailbox is him, the landlord and USPS.

“You need a key to access any of these individual mailboxes and the only person who has the master key I would assume is USPS," said Walls.

Walls says he's filed a complaint with USPS. News 12 reached out to see if they are investigating the matter and has not heard back.
