Home aide batters 95-year-old grandmother over the head with a saucepan until she collapses in her New York City home - while her horrified family watched the attack unfold on cameras

A healthcare worker is being hunted by police after she bashed an elderly woman with a saucepan in her own home.

Dorothy, 95, was being cared for by the female assistant from Medflyt at Home Health Care Agency on July 21 when she was attacked.

Her daughter and granddaughters watched the attack live through cameras they installed around the apartment in Harlem, but were powerless to stop it.

Video showed the Medflyt in a rage, yelling 'You p**sing me off' at Dorothy before violently throwing two objects in her direction.

Later in the video she hit her with a saucepan, which Dorothy blocked with her arm, then threw the pot over her head.

Then the carer came back at Dorothy with another pan, repeatedly bashing her over the head with as she clung to her walker, until she fell to the floor.

Dorothy was battered and bruised by the attack, has trouble lifting her arms, and is still in pain with doctors concerned about possible blood clots.

Her daughter Ramona Mitchell was away from the apartment and got a call from her daughter, who was watching the attack on her phone.

She said her other daughter Tiffany called Michelle and said her grandmother was being attacked, and she called Ramona in tears.

'Tiffany just told me that the girl beat her up, Michelle was crying and screaming on the train 'oh my God, grandma's been beat up',' she told ABC 7.

Michelle said watching the 'horrific' attack was a 'nightmare' and one of the worst days of her life.

'I felt helpless... it was the worst thing I could have imagined,' she said.

'It was so unreal to me, that someone could punch somebody like they were beating them down.'

Police are looking for the worker, but have not yet found her to make an arrest.

'We're doing an internal investigation, alongside the New York City Police Department, and are cooperating with authorities,' Medflyt said.
