Footage shows the man watching a 67-year-old woman during her transaction at Union Bank.

Police say the man followed the women her residence in the 3000 block of 10th Avenue and forcibly took her purse.

KCAL9’s Rachel Kim spoke with the victim, who wished to be identified only as Norma.

“Just being an older person, it is so sad to see a young man robbing you,” she said. “I never thought somebody was checking me.”

Norma said she exchanged hellos with the man before he grabbed her from behind and told her “this is a robbery.”

She says her head started bleeding as she fell to the ground during a struggle. That’s when the suspect took her purse and drove off with her cash and sense of security.

“We were struggling here… That’s how I believe I hit my head,” she said. “Now I’m afraid, especially at night, I feel like dreams like he might come and get me.”

He is described as a black male in his 30s, about 6 feet tall and 250-300 pounds, with black hair, brown eyes and a full beard.
