CLARKSVILLE, Tenn. (AP) — A Clarksville couple concedes their tiff was over feeding their pet guinea pig. After that, the stories differ.

Police charged 31-year-old Emmanuel Igbokwe with domestic violence and simple assault Tuesday evening after his girlfriend said he pushed her while she was walking down stairs. The Leaf-Chronicle (http://leafne.ws/SAqOTk ) reported the victim did not fall.

Igbokwe told police the couple argued over the pet, but denied touching his girlfriend. He was released on $250 bond.
