More than 50 people stood by and watched as a man beat his daughter to a pulp.
The incident happened on Thursday in the southern Indian city of Bangalore, a well-known IT hub.
The man is believed to be a police officer from the neighbouring state of Tamil Nadu.
He heard that his daughter, a woman in her early 20s, was dating someone and decided to take it out on her near a busy flyover, The Times of India reported.
The woman's mother reportedly did nothing to stop the abuse.
Eventually, two women - Ms Niveditha Chakraborty and Ms Archana Sharad - came to the victim's rescue, by taking her into their car, said the report.
But the father sat on the bonnet and did not allow them to drive off.
The two women called the police, and help arrived about 30 minutes later.
They were going for breakfast when they saw the incident.
Ms Chakraborty told Times of India: "We were shocked to see this man, well-built, kicking a girl in her groin repeatedly in public. We got off the car and my friend tried to push him away, while I tried to remove his hands from her hair."
She claimed none of the people who had gathered made any attempt to help them.
She said: "In his attempts to resist, the man was pushing us as well."
Ms Chakraborty said there was a young man standing by, trying to help. Once they freed the girl, they asked him to help her get out of there. She said: "He had a helmet in his hand, so we told him to take her away on his bike. But then the father removed the key from the bike."
Desperate to get her out of the dangerous situation, both women tried to flag down an autorickshaw (a three-wheeler taxi) but the father stopped them.
In desperation, they locked themselves in their car for over 30 minutes along with the battered woman.
Said Ms Chakraborty: "We wanted to get out of there, but he sat on the bonnet.
"There were so many people standing by. If one of them had removed him from the car, we could have taken her to safety. But no one did."
The victim told her rescuers her story while the three were in the car.
Said Ms Chakraborty: "She (the victim) said her father dragged her out of the hostel and started attacking her. She kept saying the rumours weren't true, but he wouldn't believe her."
The report said the daughter did not want to file a police complaint against her father and he was let go.
In a Facebook post that was widely shared, Ms Chakraborty wrote about the incident.
"He is a cop and he was beating up his daughter mercilessly. And then you have a crowd of people who are watching the drama without moving an inch. Makes you wonder what sort of society we live in."
