Human remains found in a West Yorkshire river are those of missing Bradford woman Suzanne Blamires, police say.
They were recovered from the River Aire, Shipley, on Tuesday after being found by a member of the public.
A man thought to be PhD criminology student Stephen Griffiths, 40, is being questioned on suspicion of murdering Ms Blamires, 36, a prostitute.
He is also suspected of killing two other Bradford sex workers, Shelley Armitage, 31, and Susan Rushworth, 43.
A West Yorkshire Police spokesman said: "Examination of human remains recovered from the River Aire have confirmed a positive match to Suzanne Blamires.
"Inquiries into the incident remain ongoing."
CCTV footage is understood to be playing a major part in the investigation.
