One witness told CBS Miami the woman was hit dozens of times during the apparent abduction.
Detectives are seeking the public's help in finding the woman and her abductor.
Witnesses said the woman tried to hide in a restroom.
Police are on the hunt for a man seen beating and abducting a woman from a Miami auto shop Friday night. Shortly after she walks in, the woman can be seen being dragged out by a male.
"He takes her from the restroom and hit her like, I don't know, 20 or 50 times", the witness, who did not want to be identified, told the station.
The video shows the man walking the woman outside with his arms wrapped around her neck and forcing her inside the vehicle. She is described as being in her mid-20s to early 30s, and is between 5 feet 4 inches and 5 feet 8 inches tall.
"This is someone's daughter, someone's sister, someone's family member", Cruz said. Miami police commander Freddie Cruz characterized the footage of the incident as "very disturbing" in a statement released on social media. We need to apprehend this individual. The vehicle is being described as a newer model white Nissan Altima bearing a paper tag.
Anyone with any information is asked to contact police at 305-603-6370 or 911.
