A 64-year-old woman was left in a coma after she was brutally attacked by a man who choked her till she became unconscious and then raped her.

A 38 year old sex predator known as Frankie Harris, has been arrested over the weekend for the brutal attack on a 64 year old woman in New York.

Surveillance video obtained by cops shows the attacker rode past the woman on a Citi Bike, parked it between two cars then came up to her and had a seconds-long conversation that appeared to be “amicable,”

The friendly approach may have been a ploy to get her to let her guard down.

The incident which happened in East Harlem, New York on May 18 and was caught on camera shows Harris choking the woman from behind, wrestling her to the ground and sexually assaulting her just steps away from her home near 111th Street and 2nd Avenue, East Harlem, New York.

After sexually assaulting the elderly woman, Harris then washed his hands and left the scene on a bicycle, with the woman’s face buried in a pool of her own blood and feces.

The woman has been taken to the hospital after the attack and put into a medically induced coma so she can recover.

According to The New York Daily News, New York City police released a photo of the suspect and surveillance footage from the attack leading to his arrest.

Police said they believe Harris is mentally disabled and is an addict of K2 – a synthetic drug made to resemble marijuana which can have unpredictable effects on users.

Once he was taken into police custody, Harris reportedly told officers, ‘Yeah, I did it. It was consensual.’

Police have now charged Harris with attempted murder, rape, strangulation and sex abuse in connection with the attack.

The victim’s son has spoken out following the attack and said he hopes Harris gets the maximum punishment for the heinous crime Harris committed on his mentally disabled mother.

‘I hope he rots in prison. I’m going to make sure,’ Kristian Delgado, 37, told The Daily News.

‘She was loved by everyone. She had a few issues, psychiatric issues, but everybody who knew her loved her,’ he continued.
