Julian Harris, a rookie officer in the Dallas Police Department's South Central Patrol Division, was arrested Thursday morning after police were called to meet with an injured woman at Dallas' Charlton Methodist Hospital.

DPD detectives say that a fight between Harris and the woman at Harris' Dallas apartment escalated into violence that left the woman hospitalized with serious injuries.

Harris was booked into Dallas County Jail just after 11 a.m. for aggravated assault. An emergency protective order was also issued to keep him away from the woman.

In May, just nine weeks after Harris graduated from the police academy, he and another officer were praised for helping rescue a group of hooky-playing boys from a flooding creek. Dallas News | myFOXdfw.com
