The son of a woman who was flung into the air with her two grandchildren in a hit and run today called for the “scum of the earth” to be brought to justice.

Khalida Bibi, 57, was crossing Central Park Road, East Ham, with her four grandchildren when a hatchback ploughed into them at speed.

Horrifying CCTV footage shows Mrs Bibi and two of the children being thrown four metres down the road before she hits a bollard. Two men can be seen running away from the vehicle.

Mrs Bibi was rushed to hospital after breaking both her legs, two ribs and suffering head injuries during the crash last Thursday, shortly before 3pm.

Her 11-year-old grandson who broke his nose and 10-year-old granddaughter who was bruised and scratched have since been released from hospital.

Her son Asad Shan, a creative director at a media company, told the Standard: “It’s frustrating the guys ran off and left two little kids and my mother. It’s outrageous and appalling for humanity.

“If anything else it shakes your faith in humanity – what kind of people live in this world? They didn’t even check to see if they were dead or alive.

“I always believe in humanity – these two guys are the worst scum of the earth and deserve to be punished very severely.

“I hope the law will severely punish them- they have to pay the price for what they have done to our family. I’m sure we are scarred for life now. This changes everything. My mum already has arthritis and is a survivor of a brain tumour.”

Mr Shan it was a “miracle” they all survived and that his mother saved his niece and nephew by taking the impact of the hit.

He said: “My mother broke both her legs, two ribs and damaged a lung. She’s had 12 stitches in her head. Obviously she’s got scratches and bruises everywhere.

“It’s no less than a miracle. We have been very fortunate and lucky.

“My parents lived on that road for over 40 years. Obviously the children are quite numb and have been crying. It’s a life-changing incident for us.

“If anyone knows these guys or recognises them please contact the authorities. How can they do this to innocent people?”

Mrs Bibi is expecting to undergo surgery on her legs this morning.

A spokesman for the Met said: “Police were called at approximately 3.55pm, on Thursday, 27 October to reports of car in collision with three pedestrians in Central Park Road.

“Officers and London Ambulance Service attended and the three pedestrians - a woman aged in her 50s and two children, a boy, 12, and a girl, 11 - were taken to hospital for treatment.

“No arrests have been made an enquiries are continuing.”

Police have asked for anyone with information to call 101.
