Police say a 22-year-old man arrested in connection with the disappearance of Georgia Williams is 'known to her'.
Superintendent Nav Malik from West Mercia Police said the man currently in custody was "a friend" of Georgia's but added he was not her boyfriend.
Georgia, 17, had been due to attend a music concert with her boyfriend this week, and she also missed her first driving lesson, said Mr Malik.
