A 30-year-old man who punched an elderly woman in the back was arrested and now faces misdemeanor assault charges.

The 78-year-old woman, Donna Holman, said she was protesting abortion near a Planned Parenthood office on Wednesday morning when Man Chun John Ma, an international graduate student at the University of Iowa, hit her in the back and then walked away without saying a word, according to The Blaze.

Ma’s punch allegedly knocked Holman forward and caused her to drop her anti-abortion sign. Holman and her husband have been protesting at Planned Parenthood locations for decades and have reportedly had people hit them and throw things at them in the past.

From their experience protesting, the Holmans learned to carry around cameras and walkie talkies with them. So when Ma hit Donna, she was able to contact her husband Dan immediately.

Dan then pursued Ma with his camera, called 911 and detained him until police came to arrest the international student.

Dan’s confrontation with Ma — including Ma’s apology for his actions — was caught on video.

“Sorry about that … I know I’m in trouble,” Ma said to Dan when asked if he hit Donna.

Ma also later tells police that, “I did punch her … that was probably wrong.”

The arresting officer’s comments are also included in the video, as he tells Dan that he and his wife were looking to provoke bystanders with their protest signs.

“Listen, you and I both know why he did it,” the officer said to Dan. “He doesn’t like the sign. I personally don’t like the sign … he was extremely offended by the sign … you’re looking to provoke an extreme reaction with that. I don’t have a problem with what you’re doing; I don’t like it … but that doesn’t mean that what he did was OK.”

Ma said he hit Donna because “found the idea of being anti-abortion strange.” He also said that he knew his actions were wrong.

Because of his arrest, the international graduate student might also face repercussions with the University of Iowa. His immigration status could also be affected.

Ma was released from jail Wednesday and is set to appear in court Sept. 11.
