Police have now arrested five people – two on suspicion of murder and three on suspicion of kidnapping. The most recent arrest was a 33-year-old man who was held on suspicion of kidnapping on Saturday. Four of those arrested were released on bail. Owami was last seen in the early hours of July 7 walking along Derby Road, West Croydon. She had left her family home in Grays, Essex, three days earlier. Detective Chief Inspector Nigel Penney, who is leading the investigation, said: “This is a complex ongoing investigation involving a significant number of officers. “We are working tirelessly to follow every line of inquiry, including extensive CCTV footage, as we continue to search for Owami. “We are now a month since her last confirmed sighting. I can’t imagine what that time has been like for her family. We continue to give them all the support we can. “I am grateful for the help we have received from the public so far, but I must again appeal to anyone with information – no matter how insignificant they think it may be – to get in touch.” The Met’s Special Crime Squad is leading the investigation to find out what happened to Owami. Anyone with information is asked to contact the incident room on 020 8721 4622.
