Police Officer Matthew Plummer was charged after confronting a man who he says threw a bottle at a bus and exposed himself.
Altoona police have since reassigned Plummer and on Thursday, Plummer's lawyer told WTAJ his client was simply acting in self-defense.
"The individual took a swing at Mr. Plummer," said Steve Passarello, Plummer's attorney. "He missed and Mr. Plummer simply defended himself, hit him with one punch and knocked him to the ground."
A preliminary hearing for Plummer in Washington County is slated for later in September.
