Following a dispute between an Oklahoma Highway Trooper and paramedics that was caught on tape, both sides defend their case.

The trooper in question identified in newly-released documents as Daniel Martin is under investigation tonight by his own department.This comes one day after video of him trying to arrest a Creek Nation paramedic in the middle of a transport made headlines nationwide.

It's the video shows a violent confrontation between first responders outside of an ambulance, as a patient inside waits for medical care.

Watch the raw footage of the fight captured on a camera phone.

Now Trooper Daniel Martin, who placed his hands around the neck of a paramedic, is now the subject of an internal investigation, although he and his partners remain on duty.

"The highway patrol officers, the troopers, are not being placed on any kind of administrative leave," OHP Captain Chris West said. "If the investigation shows there were some violations of department policy or procedure, we'll address those accordingly."
