Police are questioning a 40-year-old man on suspicion of murdering three prostitutes after the body parts of a woman were found in a river.
The man was arrested on suspicion of the murders of missing Bradford sex workers Suzanne Blamires, Shelley Armitage and Susan Rushworth, West Yorkshire Police said.
The remains of the woman, who has not yet been identified, were discovered by a member of the public in the River Aire, in Shipley, West Yorkshire, at about 2pm on Tuesday.
Assistant Chief Constable Jawaid Akhtar said police had been granted extra time, until Thursday evening, to question the 40-year-old man, who was arrested on Monday.
Speaking at the scene of the discovery of the body parts, Mr Akhtar said: "It is a very thorough and painstaking inquiry into three missing women, all of them sex workers, with all the necessary resources and expertise devoted to it."
He said the families of the three women were all being supported by police family liaison officers.
The remains were found in the water just a few yards from where the busy Otley Road dual carriageway crosses the Aire.
Screens were erected on either side of the bridge and forensic work continued in the small industrial estate where the tents have been put up.
People living and working in the area said the officers had been examining a number of derelict buildings in the past few weeks and had been searching the area for days.
