How's that for a knuckle sandwich?

Police in Upper Darby, Pennsylvania are looking for a man who allegedly punched a customer in the face for looking at his teenage daughter while at Wawa, according to MyFoxPhilly.com.

The incident happened around 5:15 p.m. on Sunday on 69th street, according to reports. A 47-year-old man was ordering a sandwich at the touch screen when the dad accused him of checking out his daughter, then sucker-punched him in the face, Philly.com reports. He remains hospitalized.

"The man ordering the sandwich said he wasn't looking at the guy's daughter. And the guy sucker punched him, knocking him to the ground," Upper Darby Superintendent Michael Chitwood told Fox.

The dad and his daughter took off in a dark colored Ford, police said.

Anyone with information on the two is asked to call Upper Darby police at 610-734-7693.
