I have name changed as this will out me to those who know me.
My SS is 15, nearly 16. For the last 6 months or so he has been taking things that are not his. It seems that if he wants something, no matter what it is or who's it is, he just takes it. When you find out and ask him why, he just says "I dont know"
The things he has taken have been christmas chocolate (which he took out of the top of my cupboard, and when pressed as to why, he said he thought it was a free for all (which is a lie as he took it from the back so it wasnt noticed). Food out of the cupboard (which has then just gone moldy in his room) - no reason for this given. Money that is left lying around, but as he denys it and we have no proof, nothing we can do. My DH bought himself a new pair of trainers, which he took a liking to, and then just took them (wore them, stretched them and ruined them) A sim card went missing with alot of credit on it (over £150) which again we had no proof of, but we are 99% sure it was him. And the most recent was he took his DMs bank card, and helped himself to £20 out of her bank. He denied it was him, until his DM threatened to call the police, to get the CCTV footage of whoever did take it - he took this as apparently his DM didnt give him any lunch money, and he didnt want to starve.
What can we do about this, he is currently grounded, and has no phone etc but really need a way to stop him doing this. Any ideas?
