The family had been out walking in Ruislip, West London on Sunday afternoon. The mother of 22-month-old Xixi said “we didn’t stand a chance”.

She said that they first saw the car mount the pavement then it smashed into them while still driving on the pedestrian walkway.

The 31-year-old mother carried on to say that her husband had been pushing the pushchair and that the car was speeding along the pavement so fast they couldn’t get out of the way in time.

Paying tribute to her daughter she said that “She had the most beautiful smile, and her eyes were always full of love and laughter. She was our angel, our everything and there isn’t a moment that we could stop thinking about her.”

During the horrific incident she suffered a leg injury while her husband needs surgery on his arm.

Alan Newton witnessed the accident and said “It was horrendous. The father had a damaged shoulder and head injury. The pram was completely crushed. There was no hope for the little one. The mother was shouting, ‘my baby, my baby’ over and over again. The father was just distraught. The paramedics came and the police, some of whom couldn’t look it was so distressing. They held their heads in their hands. They said it was the worst thing they had ever seen.” Police have said that a man in his forties has been arrested for dangerous driving and driving while under the influence of drugs. Emergency services tried to save the little girl’s life but she was pronounced dead at the scene. Witness Mr Newton, 61, added that “This poor family were on the pavement walking home from their routine evening trip to the park. It’s a tragedy.”

The family are currently being supported by specialist police bereavement officers and flowers have been laid at the scene of the tragic accident.
