Det Insp Trevor Ord, of Newcastle police, said: 'We can't rule out that it was a copycat attack. The circumstances are similar and we have been liaising with colleagues at Lanchester.'
The 13-year-old was assaulted on Christmas Eve, but was too frightened to report it until this week. The girl escaped injury, but was shocked by her ordeal. The assailant, in his mid-twenties, fled when he heard voices near by.
