Cops said 52-year-old Lisa Arnold may have attempted to kidnap another baby from a stroller just 20 minutes before the incident.
It's the harrowing 911 call of a brave California boy who describes saving his 2-year-old brother from an attempted kidnapping just moments before.

The 8-year-old was with his mother and 2-year-old brother by a Glendale elementary school when cops said a stranger approached the family, and tried to kidnap the toddler.
"He said, 'You have a beautiful kid,' and tried to get the baby out of our hand," the boy could be heard saying to the 911 dispatcher.
While it was originally the boy's mother who called police, the dispatcher asked the woman to pass the phone onto her older son due to her heavy accent.
The boy was up to the task, and replayed the scene to the 911 dispatcher.
"It didn't happen to me, it happened to my little brother," he explained. "He was walking, sneaking past us and trying to get the baby out of our hands. And then she hit my mom, and I said 'let my brother go' very strongly."
The boy then said he was able to push the attacker off and keep his brother safe, but the attacker got away.
"We were guarding my little brother, so she couldn't take him," said the 8-year-old, whom police are asking media to keep unnamed.
When the 911 dispatcher asked the boy to describe the attacker, the boy responded: "He drives a small, gray car. It was a man, it looked like a lady. We weren't sure. Her, his voice looked like a girl but he looked like a man."
According to a press release by the Glendale Police Department, a similar incident was reported just 20 minutes earlier.
A mother was taking a walk with her infant child, who was in a stroller, when what appeared to be the same attacker approached the pair, and grabbed the child out of the stroller, surveillance footage showed.
The attacker, whom police later identified as 52-year-old Lisa Arnold, could be seen in surveillance footage running back to her silver car empty handed after a struggle with the distraught mom.
