Megan Welter, an Arizona Cardinals cheerleader and former Iraq war veteran, was arrested after beating her boyfriend, Ryan McMahon, over a suggestive text he sent to a former girlfriend, The Daily Mail reports.

Although Welter was the one to call the police after she requested help getting her boyfriend, a professional fighter, to leave her house, officers arrested Welter after McMahon provided video footage on his cell phone that showed the 29-year-old cheerleader attacking him.

Their argument allegedly began on Saturday, July 20 after the couple, who had dated for six months, went out to celebrate Welter's birthday at Whiskey Row in Scottsdale. They had both been drinking.

Once the couple returned to Welter's home, they began to argue about the text message he had sent.

A former girlfriend texted McMahon a picture of a dog and he responded with, "Are you trying to turn me on with a girl dog?" Afterwards the altercation reportedly began, some of which can be seen of McMahon's phone.

Welter begins by asking him "Who is she?" several times and then scratches him and pulls his hair as he asks to leave. He maintains that he never touched Welter.

However, in the 911 call, Welter claimed that McMahon choked her and smashed her head against the floor.

Welter has no physical marks from the incident but McMahon has scratches on his arm, chest, and shoulder. Welter admitted to cutting up his credit card and ID which was later found on the kitchen table by police. She claims to have cut them while her boyfriend was outside of the house, picking up his belongings that she had thrown out.

Welter served in the armed forces for 16 months and led a platoon in Iraq.

McMahon said in a statement why he did not want to press charges:

"People make mistakes, no one is perfect. I honestly want the best for her and I hope that this doesn't take away from the good things that she has done for both the NFL, as well as the service to our country. People seem to only remember the bad and it is easy to point fingers while standing on the outside. Now with that said, violence is never the answer and I honestly hope that this can be a learning experience for her and everyone else."
