Six weeks on from her disappearance, police say they are carefully studying 40,000 hours of CCTV footage
Six weeks on from the disappearance of Owami Davies, the Metropolitan police says it still has 40,000 hours of footage from CCTV cameras and other devices to go through in its search for the student nurse.
If not quite seeking a needle in a haystack, the force insists it is devoting huge resources and elite detectives to finding one person in a city of more than 8 million, unsure if any crime has been committed.
Anyone with information can call the police on 020 8721 4622, or to remain anonymous contact Crimestoppers on 0800 555 111 or online.
