One person was arrested and authorities are looking for a second suspect after they made up a story about a home invasion to cover up an assault on a 73-year-old woman, a sheriff's office said.

Deputies from the Rowan County Sheriff’s Office were called on Wednesday to a home by a woman who told them she had returned to the home to find her boyfriend’s mother badly beaten, news outlets reported. The woman told deputies two men had come to the back door of the house while the victim was home alone, forced their way in and then beat her severely before leaving, the sheriff's office said.

The victim was taken to a local hospital before being transferred to a Winston-Salem hospital with life-threatening injuries, according to the sheriff's office. The sheriff’s office said the victim’s attackers used a broken cinder block and the handle of a hydraulic floor jack to beat the victim for approximately five minutes.
