Detectives from the Metropolitan Police’s specialist crime unit continue their extensive enquiries to find missing student nurse Owami Davies.

Officers have searched houses and parks, viewed hundreds of hours of CCTV and conducted extensive door-to-door enquires, but still Owami, from Grays, remains missing.

Five people have been arrested in the course of the inquiry – two on suspicion of murder and three on suspicion of kidnap.

Detective Chief Inspector Nigel Penney, who is leading the investigation, said: "The sheer scale of this inquiry shows how concerned we are for the safety of Owami.

"With every day that passes that concern only grows and our fear increases that she has come to harm.

"Although this is a missing person enquiry, this is one of the biggest investigations I have ever experienced and that reflects our determination to find Owami for her family.

"Owami has now been missing for over a month and her family are desperate for news.

"We are keeping them fully informed, but finding Owami is the only thing that will bring them any peace and for that we need the public’s help.

"I want to thank the public for all the support we have already received, but I continue to appeal for anything that could assist our inquiry.

"Please call if you have any information - do not talk yourself out of telling us what you know. If you think you may have information about Owami, trust your instincts and call."
