Cops: Cross guard beats taunting teen

Here’s one crossing guard you don’t want to cross.

Gerald Kelly, a 6-foot-2, 200-pound crossing guard at Drexel Hill Middle School was arrested last week for beating up a 14-year-old boy who’d called him names, according to police.

Kelly, 60, was off duty and coming out of the Shadeland Pharmacy, on Shadeland Avenue, Thursday afternoon when he saw the teen sitting on the steps outside, Upper Darby Police Superintendent Michael Chitwood said.
