The Los Angeles County Sheriff's Department said the suspect allegedly grabbed the girl's arm and pulled her as she walked through the park.
A Good Samaritan intervened and threatened to call police, authorities said.
That's when the suspect let her go, but not before authorities said he allegedly reached for a child that was with the Good Samaritan, but was unsuccessful. He ultimately took off running and remains on the run.
