Binjore, Jan 12 (NDTV): In CCTV footage from a home in Uttar Pradesh, an elderly woman is seen cowering in her bed as she is slapped, kicked, choked and beaten with a brick. Her attacker is her own daughter-in-law.

Sangeeta Jain was arrested this morning for attempted murder after the video of her vicious assault on her 70-year-old mother-in-law Rajrani Jain went viral on social media. The camera had been secretly installed by her husband.

The disturbing visuals are from January 5, when only the two women were inside their home in Bijnore.

Sangeeta is seen mercilessly beating the older woman, trying to strangle her with a cloth, dragging her by her hair and slapping her repeatedly. She pauses only to get a brick and then starts raining fresh blows, jumping on the bed in what appears to be a frenzy. Throughout the assault, her mother-in-law clings to her quilt for dear life.

"She came out of the kitchen and started slapping me. She also started to beat me with bricks...I do not know why she does it," said a badly wounded Rajrani Jain, her head wrapped in bandages.

Her son Sandeep has been married for seven years to Sangeeta, who recently filed dowry harassment and marital rape cases against him. A divorce is now in process.

"She was always like this. She used to attack us all - my parents, me..." Sandeep Jain told reporters. He couldn't explain why he waited this long to go to the police.

"I waited for a year and then thought of installing a CCTV camera to expose her," he said.

He claimed that when he went to the police first, they said they could not take action against a woman.

Sangeeta claims that the video is fake. "They said they would throw me out. They made this fake video to ruin me. Did they make a video when my in-laws beat me?" she said.

Senior police officer Daljit Chowdhury said: "It is a pity. There is a lot of fighting in the family, it is a family dispute, but now we have the footage. We will definitely take action."
