Nathan Roy Webb, 27, of 1212 Old Apex Road, was arrested Wednesday and charged with felony child abuse. He was being held Wednesday in the Wake County jail under $500,000 bond.
According to an arrest warrant, the child suffered multiple fractures, including a broken leg.
The alleged offense occurred between May 15 and June 1.
In a domestic violence protective order obtained against Webb on June 10, Heather Upchurch accused him of breaking through a locked door and threatening her over the child. She said she noticed something was wrong with the baby on June 1, and emergency room physicians determined the child had a broken leg and other bone fractures, according to court documents.
