Owami Davies, 24, from Grays, Essex, was last seen shortly after midnight in Derby Road, West Croydon, south London, on Thursday July 7. An unconfirmed sighting placed her on nearby Clarendon Street at 7am. later that morning. The Metropolitan Police said she had left her family home in Grace three days earlier on Monday, July 4. Police arrested five people – two on suspicion of murder and three on suspicion of kidnapping. The latest was a 27-year-old man who was arrested on suspicion of kidnapping on Saturday. Four of those arrested were released on bail. DCI 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 it was like at that time for her family. We continue to provide them with whatever support we can. “I’m grateful for the help we’ve 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.” Investigators had previously appealed for the driver of a white van which was parked in Derby Road when Owami was last seen. She and a man crossed the street just as the van pulled out. Owami’s mother Nicol Davies has made public appeals through the police for help in finding her daughter. He said: “This is such a terrible time for everyone who loves Owami and I am asking anyone who can help find her to contact the police. “Every day we hope to hear the news that Owami is coming back to us, your help can make it happen.” Miss Davies was nearing the end of her studies and had secured a job with Guy’s Health and St Thomas’, her mother told the PA news agency. He had worked in A&E during the Covid-19 pandemic and was interested in doing disease research.
