According to The Community Press: On Wednesday, May 3, Ohio Mail Carrier Joshua Griffin-Ayers was delivering along his route when he saw a group of about 14 preschoolers on their way to the library. He also saw the growling pit bulls headed their way.

“I tried to warn the teachers, but there wasn’t any time,” Griffin-Ayers said.

He then got between the dogs and the children and used three cans of pepper spray on the canines while the children safely crossed the street.

Griffin-Ayers was recently recognized for his efforts by Cincinnati Postmaster Chu Falling Star as a kick off to the Postal Service’s National Dog Bite Prevention Week.
