"They're relieved that there's someone who caused harm to their grandmother, and this person could harm another person," said family spokesperson Cynthia Choi.
San Francisco Police reports 18-year-old Keonte Gathron was arrested Saturday in San Francisco after committing another robbery. Details of that crime are unclear.
Police believe Gathron beat Mrs. Huang the morning of Jan. 8 in a park in Visitacion Valley, before breaking into her home across the street.
"I'm glad a suspect was apprehended, this is a heinous crime and doing this to a senior is unheard of," said San Francisco Supervisor Shamann Walton.
Huang's family says she remains in critical condition, with a shattered face along with a broken spine, hand and ribs.
The crime shook the community and a safety forum was held on Saturday. Police assured neighbors they've increased patrols.
"Anybody who comes to our community to harm a senior or child, we're gonna find them," Walton added.

Grandma Huang's family says there are signs she is improving.
"She's reacting to family members on their visits, a slight improvement, they're very hopeful what they are seeing," Cynthia Choi added.
Suspect Keonte Gathron is being held in the San Francisco County Jail. He denied an interview request by ABC7 News on Sunday.
The San Francisco Police Officers Association is offering a $10,000 reward for the arrest and conviction whoever assaulted Huang.
And Yee has organized a fundraiser to raise money to increase the reward or to help with her grandmother's medical bills if no reward is collected.
