Parents think a dangerous underpass should be closed before another person is hurt after an elderly lady was left fighting for her life.
Residents of Carlyon Road, Hayes, and parents of pupils at Yeading Infant and Junior School, thinks something needs to be done to stop people getting attacked in the underpass under the A312 Hayes bypass, which is just yards from the school.
Their calls for safety measures have come following the attack of Valerie Dancer at 2.45pm on Tuesday.
It is believed the 63-year-old, who lives nearby, was walking home from a friend's house when she was robbed in the underpass.
Lisa Cookson, 39, has children who attend Yeading School as well as a teenage daughter.
She said: "That is the third attack under there. There was an attempted rape about 18 months ago and there has been another attack since.
"I always tell my teenager daughter to walk with a group. There's so many mums who walk through the underpass, I just think it's appalling.
"I am moving out of this area because it's so bad. I think my kids will stand a better chance."
Janice Fisher, 48, a life-long resident of Carolyn Road, said: "It has happened before. Last Christmas a friend of mine was mugged in an alleyway further up and the lady across the road from me was mugged there in the summer.
"It's so dangerous because you can't be seen under there. You have to go down pathways amongst bushes and away from the houses. The fault is in the design. It was built about 18 years ago and there was no problems before that.
"I don't walk down there unless I am escorted and when my husband comes home from work he rings me to let me when he is at the underpass.
"If nothing is done the attacks will carry on."
Aa Diriiye, 37, has three children who attend the junior school.
He said: "A school girl got attacked with a knife in the underpass last year. It's very dangerous. I never walk under there and I would never let me children either. I always pick them up from school.
"There needs to be more police here at school time or they should just close it."
Valerie Dancer was taken to Charing Cross Hospital by air ambulance with head injuries where she remains in a critical but stable condition.
The suspect is described as a black teenager wearing dark clothing and following the attack he ran off under the underpass towards Yeading Lane, Hayes.
Officers have established that the victim's beige leather handbag and her black 'Radley' purse were stolen together with other contents of her handbag. She was wearing a beige duffle coat and blue jeans.
The officer leading the investigation DI Mark Brookes said: "Valerie's family are distraught following this appalling attack and I would appeal to anyone who witnessed what took place or has any information to contact us as soon as possible."
