Yiewsley residents are "in shock" after a brutal hammer attack on a 90-year-old grandmother - who is now fighting for her life in hospital.
A local resident, who did not want to want to named, said: "Her son had just brought her home from doing her shopping at about 6pm, then at 8pm that happened.
"The first thing I knew there was sirens going round the corner. I know the son of the woman.
"They reckon it was a hooded woman who did it. She hit her round the head with a hammer and stabbed her in the neck.
"She (the victim) had lost her husband only six or seven months ago and she's only just come out of hospital.
"But apparently she was still conscious last night because she was able to talk to the police and the ambulance but she's been sedated now.
The resident said she is a grandmother and mother or two.
"She always says good morning to us and walks past sometimes with her trolley," they said.
The residents are are already hoping to create a crowdfunding page to help the victim.
The resident added: "You can imagine she was probably just pottering about at home and putting away her shopping.
"It's just heartbreaking to think that someone could do that to anyone let alone an elderly person.
"There's of people saying they're thinking of moving from this area."
One "stunned" nearby resident had just picked up the keys to home to move in when he saw a police cordon a few hundred metres away from his new residence.
Glerild Gaxholli, a self employed construction worker, had bought the home for his expanding family hoping it would be a safe place to live.
He said: "I've just moved in to my home and I'm shocked.
"I moved from Greenwich and literally picked up the keys this morning. I thought this would be a nice place to move to.
"It's really making me worry now. I'll have a wife and two kids at home and I'll be leaving them there when I'm at work.
"My daughter, she's just two and a half years old and I have another on the way in August.
"I literally just got the keys this morning and haven't moved my things in yet.
"These things never happened to me in the eight years I lived in Greenwich, I'm just so shocked.
"I mean she's 90, why would you do this? It's 2017 why are people doing these kind of burglaries?"
There have been no arrests.
The detectives are keeping an open mind as to any possible motive, the police said.
