A Texas suspect was arrested after his loose dog mauled a 68-year-old man Saturday, police say.

Kelly Max Oshaughnessy, 33, was charged with serious bodily injury to an elderly person and attack by dangerous dog, Bexar County authorities say. His dog was seized by animal control for a 10-day quarantine period.

Bexar County Sheriff's Office says the incident took place at around 8:30 a.m. Saturday. A caller told them that her father was being attacked by a dog that was loose "after returning from a walk."

"A neighbor reported hearing screaming, when he ran outside to assist," Bexar County Sheriff's Office explained in a Facebook post. "He was able to remove the dog from attacking the victim further."
