A 72-year-old Wal-Mart greeter is in the hospital after being punched in the face by a Pittsburgh-area man.

Surveillance video shows Thomas Jenkins standing at the entrance to the Wal-Mart in a town about 13 miles southeast of Pittsburgh. A man comes around the corner, punches Jenkins in the face and the elderly man falls to the ground.

North Versailles Police Sgt. Vince DiCenzo says 55-year-old Paul Washington of North Versailles has been arrested and charged with punching Jenkins. DiCenzo says the attack appears unprovoked.

He says Washington denies hitting Jenkins.

Jenkins is being treated in a local hospital for broken facial bones.

It is not immediately clear if Washington has an attorney.
