The three Virginia Alcoholic Beverage Control Department agents involved in an arrest that injured a University of Virginia student have returned to regular duty.

The arrest of Martese Johnson caused a furor after photos and video of the bloodied 20-year-old were circulated widely on social media. Johnson, who is black, could be heard on the recordings calling the officers racist.

The ABC said in a news release Monday that its review of a Virginia State Police investigation determined that the agents did not violate policy during the arrest in March. The agents were assigned to desk duty during the investigation.

In June, a prosecutor in a separate criminal investigation found no evidence of malice or racism by the officers, who weren't charged.

Charges against Johnson were dismissed.
