DeKalb police spokeswoman Mekka Parish said the man, who is in his 70s, had been threatening his girlfriend over the telephone throughout the day.
The girlfriend called police around 5:30 p.m., saying the man fought her when he arrived at the home.
Police said the woman had cuts on her hand after the fight and fled the home.
After the man told police he would not leave without force, S.W.A.T. was called and after about three hours investigators convinced the man to give himself up.
Parish said the man, who was not identified, will be charged with aggravated assault.
