A Florida man in the midst of a contentious custody battle with his soon-to-be ex-wife strapped a GoPro to his waist because he feared domestic abuse and wanted to catch it on camera.

Last week, his wife was arrested after the GoPro caught her “intentionally striking him in the testicles.” According to the arrest report published by The Smoking Gun, the man came up with the idea to holster a GoPro camera “due to issues in the past with incidents like this.”

The two parents were at a custody exchange Thursday morning when the incident occured. The GoPro appears to capture the husband, Michael unbuckling one of his kids from a car seat when his wife, Corrine sneaks up behind him and grabs him.

Corrine was charged with domestic battery.

“This is just one of many instances where I’ve had to use the camera to either prove her guilt or prove my innocence and that’s the only reason I am carrying it,” Michael told WTSP 10 News.
