Scotland Yard has confirmed that two men, aged 23 and 27, have been arrested in the Croydon area on suspicion of murder.
They remain in custody at a south London police station while the investigation continues.
Missing for three weeks.
Detectives from Police Specialist Crime Command are now leading inquiries because they have the resources and expertise required for a complex investigation, the Met has confirmed.
Speaking previously, Detective Constable Marie Spear, from the Missing Persons Unit in south London, said: “Owami’s family have not heard from her for more than three weeks and she has not turned up to work.
“We are currently treating this as a missing person investigation. Owami was in a vulnerable state when she was last seen and we need the public’s help in piecing together her movements on the night she went missing.
“I would urge anyone who has seen her, or knows where she is, to contact police immediately. I’d also ask people in the West Croydon area to check their sheds and outbuildings and report anything suspicious or out of the ordinary.”
