(WSB Radio) A man stabbed his ex-girlfriend multiple times and her daughter once following a break-up, a Clayton County police spokesman said.

Clayton County Police Officer Kevin Hughes told WSB Radio's Jennifer Griffies the stabbing happened early Friday night at an apartment on Arrowhead Drive near Jonesboro. The mother was taken to Atlanta Medical Center and was listed in serious condition. The daughter was stabbed in the leg. Her injuries are not as serious, Officer Hughes said.

Police said they do know the suspect's name, but are not releasing it or his description.

"You got to be careful who you pick up as a boyfriend and bring into your house around the kids," witness Sabrina Nesbitt told WSB-TV. "You never know when they are going to flip out and try to hurt your or your kids. This is a product of one of those situations."

It is not known if the suspect lived with the victims.
