Andrew has been missing from Doncaster, South Yorkshire since 14 September 2007.

It is believed he has travelled to London maybe to visit museums.

There is great concern for Andrew due to his age and he is urged to call the Runaway Helpline on Freefone 0808 800 7070 for confidential advice and support.

Andrew is 5ft 3in tall, slim with collar-length, light brown hair and brown eyes. It is thought likely that he will be wearing black jeans, a black T-shirt, black trainers and carrying a black canvas satchel with patches of rock/metal bands on it.
