A neighbour has described the frantic moments he used a car-jack to free a young boy trapped beneath a car after being hit while scootering to school this morning.  Mohammed Khan acted quickly when he heard a woman screaming near his house on Ferry Rd in the Christchurch suburb of Woolston at about 8.40am today.  “I just ran down and there had been an accident,” he said.  “When I got closer, I could see a child trapped under the vehicle. People were asking me to help.”  With the child pinned beneath the car and bystanders calling out, Khan acted quickly, running to his own vehicle to retrieve a jack to help lift the car.  “I lifted the car so the child could breathe properly,” he said.  “When the vehicle was raised, the child crawled out and ran straight to their mother and hugged her.”  Khan said the child had been travelling on a scooter when they were hit.  The child is a student at nearby Te Waka Unua School.  Principal Janeane Reid said they are “very saddened” by the incident.  “We have support available for those students who witnessed the incident and the Ministry of Education has been prompt to offer further support as needed,” Reid said.  “We are very grateful for all those community members who witnessed the incident and offered help, especially those who supported and guided our other students arriving at school past and safely into school this morning.  “How our community steps up and wraps around each other during these times shows the real strength of our village.  “Our little boy is now in the hands of the professionals up at the hospital and we will support the whānau during his recovery.”  A pedestrian has been seriously injured after being hit by a car in Christchurch this morning.
