Georgia (CNN) -- A former suspect in the killing of JonBenet Ramsey was arrested early Saturday in suburban Atlanta, Georgia, after a 911 call of domestic violence, police said.
John Mark Karr, 42, is charged with battery and obstruction of a 911 call, Lt. Keith Zgonc of the Sandy Springs police said.
Karr was arrested in Bangkok, Thailand, last year in connection with the 1996 slaying of the 6-year-old beauty queen.
JonBenet's beaten and strangled body was found December 26, 1996, in the basement of her parents' home in Boulder, Colorado.
Karr was taken to Colorado, but his DNA failed to match that found on the child's underwear.
After his arrest on Saturday, Karr was taken to St. Joseph's Hospital complaining of chest pain, Zgonc said.
Zgonc said it was expected that Karr would be transported to Fulton County Jail later Saturday.
Karr and a woman police identified as his girlfriend were arguing at Karr's father's residence in Sandy Springs, Zgonc said.
