I'm waiting for my son outside his tutors in outer London in my car. Someone has been walking slowly up the road and stopping. He was in front of my car for 10 minutes. Then a car went past and he went into my sons tutors front garden. He is just stood there. Tutors floodlight keeps going off but now I can't see him. I don't think he left her garden. It's freaking me out. He's probably vulnerable but at the same time I'm scared. Got to walk in the garden now to get my son.
