Police searching for three brothers missing since Monday have arrested a man and a woman in connection with their disappearance.
Remus, Janko and David Matloch, aged 15, 12 and 10, failed to return to their foster parents' home in Sunderland after going on tea-time bike ride.
Instead, they caught a Metro train to Newcastle and were last seen leaving Central station.
The boys have yet to be found but Northumbria Police said they arrested a 34-year-old man and a 39-year-old woman at an address in Birmingham last night.
Superintendent Alan Veitch, of Sunderland Area Command, said the investigation to find the brothers was still ongoing in both Birmingham and London.
