'It was the most traumatic event - the worst day of our lives'

The parents of a boy who was trapped in a bus crash on a motorway for hours said they went through the 'worst day of their lives'.

Oliver Knott was left seriously hurt in the crash on the M53 near Hooton on September 29 last year, the Liverpool Echo reports. The 14-year-old needed several rounds of major surgery after his leg became trapped in the wreckage.

The vehicle was taking pupils to West Kirby Grammar and Calday Grange Grammar School in Wirral when it crashed. Schoolgirl Jessica Baker, 15, and dad-of-two Stephen Shrimpton, who was driving the bus, tragically died.

Ashley said: "We got a phone call from the paramedics at the site [to say] Oliver was involved in the M53 bus crash. He got his leg trapped under the front seat of the coach when it crashed.

"He was trapped in the coach for hours before they [the emergency services] could remove him from there. They took him to Alder Hey Children's Hospital where he had a ten-hour surgery. It is a lot to go through at that age. It has been a rough ride."

Calday Grange pupil Oliver's leg had been snapped in the accident, leaving him in an external fixator frame for six months and having to undergo five major surgeries. Eight months later, Oliver's leg remains broken.

Ashley said: "He had snapped his leg - the tibia - he was put in an external fixator frame for six months that held his leg
