Police have taped a property in West Croydon on the same road a missing student nurse was last seen on.
Owami Davies, 24, from Grays in Essex, left her family home on July 4 and was last seen just after midnight on Derby Road in West Croydon on July 7 but has not been seen since.
A third man, 32, has been arrested on suspicion of murder by detectives searching for the student nurse, the Metropolitan Police said.
It comes after two men, aged 23 and 27, were arrested in the Croydon area on suspicion of murder on Monday.
They remain in custody at a south London police station, police said.
Detectives from the Met’s Specialist Crime Command were searching a property in Derby Road on Wednesday as part of their enquiries.
It comes after police launched a missing persons investigation last month following Ms Davies’ disappearance and appealed for information on her whereabouts.
Announcing the arrest on Wednesday, the Met Police said: “This remains a missing person investigation and our priority is finding Owami.”
The force added: “Owami’s family are being kept updated about the progress of the investigation.”
Any witnesses or anyone with any information is asked to call police on 101 quoting reference 22MIS025307 or contact the independent charity Crimestoppers anonymously.
