YUBA CITY (CBS13) — Less than a week after coming out of the hospital after a heart attack, a 72-year-old man stepped in to stop a violent attack against a family.

Roy Chand hadn't been in a fight since high school, but he says he was ready when he saw a man with a knife threatening a mother and her kids.

"I said, 'You want your trouble? Come on you got it. Pick on me. I'm not a woman and I'm not a kid,'" Chand said.

Chand says in the moment he was feeling fierce.

"I felt like I was 10 feet tall and 200 pounds, like I'm a boxer," he said.

The family ran inside the store. The man with the knife, Onon Donley, ran off, but was eventually arrested.
