he was colliding with a scooter and then hit the curb wich was shown on cctv.
OK I looked back at it at least 10 times and I will admit it appears that he careens off something, but I can't tell what it was. I initially assumed it was a parked car but maybe you have more information.
I don't think so. The adult managed to push him and himself round the side of the building. Strange as the person who fell out of the car, walked away. Maybe shock.
