Missing 14 year old, Serena Beakhurst was found in Wandsworth, early this morning .
Serena was reported missing after she failed to return home after college on 15 December. On 2 January, a Twitter plea for help, citing lack of media coverage, was retweeted by hundreds of users including Stephen Fry and Sarah Brown.
The Twitter campaign appears to have been key in raising the profile of the search after police admitted they had exhausted "normal lines of enquiry" earlier this week.
