Ali Fikri, 16, was reported missing from his home in Wolverton Road, on August 4.
He is Asian, slim, around 5ft 10ins, with short black hair and brown eyes.
PC Matt Stokes, leading the search, said: “Every effort has been made to locate Ali through his known contacts across the UK, however we are yet to confirm that he is safe and well.
