Los Angeles Police said a homeless man pushed a woman into a garage before trying to rape her and then he moved on to assault another woman in broad daylight.
Police said the first attack occurred at about 12:30 in the afternoon on Tuesday.
Security video of the attack showed a man with his hand around a woman's neck walking her through the driveway of a home. Moments later she is seen running away from him and he runs off in another direction.
Police said that he threatened and tried to rape the woman in the garage.
The video shows her flag down a vehicle. The driver of the vehicle was Aron Colbert, who spoke to KTLA about what happened.
"The woman was hysterically crying in the middle of the street, so obviously I had to stop. And she just jumped into my car," said Colbert. "And she said a man just tried to attack me."
Colbert said the woman called her mother on her cellphone.
"She told me a man pulled her into a house nearby and told her to take off her clothes," he continued.
Colbert drove her to a sheriff's station to report the attack.
"It was so sad because she was so shaken up and she called her mom and was just hysterically crying," he added.
Investigators believe the same suspect assaulted a second woman about 20 minutes later in West Hollywood. They said he shoved her into her apartment but she screamed and he ran away.
Police are searching for the man that they described as a transient in his early 30s wearing dark clothing and carrying a bag.
"You know I've lived here a long time and it's just sad to see this city in this sad state. You can't even walk down Melrose street anymore," said Colbert.
"Women can't even be safe on our streets," he concluded.
