A 16-year-old boy has appeared in court charged with causing grievous bodily harm to a 10-year-old girl who was left with 'serious injuries'.
The girl was reported missing from her home in Stockton on Saturday 7th April 2012 and was later found by a member of the public.
She remains in Newcastle's RVI hospital with serious but non-life-threatening injuries to her head.
The RVI Hospital has a specialist paediatric unit where a thorough examination is in progress.
The girl is approximately 4ft tall with brown hair and was wearing black leggings, a chequered top and a brown furry body warmer.
Police say they would particularly like to hear from anyone who saw a girl matching this description, either alone or with someone else between 5.00pm and 9.00pm on Saturday evening.
