It's not everyday Sioux Falls police get a call about a car hanging off a retaining wall but that's what they responded to on Thursday morning. Upon further investigation, officers learned that witnesses identified a 56 year-old man that caused the accident, and it didn't stop there.

Apparently, David Lee Yocum then approached the victim's car with a hammer and threatened him.

The victim, a Sioux Falls dentist, suffered minor injuries.

Yocum also followed the dentist to his office on Lyncrest Avenue, and then ran into him with his car, and then posted a video of the incident on his Facebook page.

David Yocum was arrested and charged with two counts of aggravated assault.
