Authorities in one Pennsylvania county are advising people not to put mail with cash or checks inside a dropbox outside a particular post office.

The Cheltenham Township Police Department says the box, outside the Elkins Park post office on Ashbourne Road, has been a target for money-hungry thieves, according to FOX 29 Philadelphia.

The mailbox has reportedly been struck by thieves dozens of times.

"Checks taken from the mailbox have been stolen, washed and fraudulently deposited into another account of an unintended recipient. The department has reported at least 70 mailbox thefts, with many happening at the Elkins Park Post Office box," the TV station states.

Police are recommending people take their mail inside the post office branch to hand it to a clerk or use a mailbox that has a surveillance camera.
