A Pennsylvania man faces charges after he mocked and then sucker-punched a person with cerebral palsy as he left a convenience store.

Barry Baker, 29, of Coatesville, was charged with simple assault after a May 10 incident outside a 7-Eleven in West Chester, Pennsylvania.

Authorities said Baker was caught on video imitating how a 22-year-old man with cerebral palsy walked from his car into the store.

When the man emerged from the store, Baker continued to mock him and then punched him in the face without warning, according to news station KYW-TV.

“The defendant’s actions in this case are appalling. You wonder what would make an individual treat somebody like that,” West Chester Police Chief Scott Bohn told KYW-TV.

Baker fled the scene and was later arrested. He posted bail and is next scheduled to appear in court on May 30.

“This defendant is a bully. Every decent citizen should be outraged by the defendant’s conduct. The victim is to be commended for keeping his cool and notifying the police,” said Chester County District Attorney Tom Hogan.
