POLICE hunting for missing nightclubber Sian O’Callaghan said they had found her body and that of another murder victim.

Detective Superintendent Steve Fulcher, leading the murder inquiry, said a 47-year-old man had been arrested on suspicion of kidnap and two murders.

The news came hours after police seized a green taxi which was seen early on Saturday when Miss O’Callaghan, 22, disappeared after leaving a nightclub in Swindon.

The Toyota Avensis estate with taxi markings was seen between 3am and 4am and 12pm to 9pm on Saturday between Swindon and Saver-nake Forest where police have been searching.

At a press conference last night Mr Fulcher said: ‘‘A 47-year-old man from Swindon is in custody, having been arrested for kidnap and two murders.

“The location of two bodies have been identified to me by this individual, one of whom has yet to be identified formally, but I am quite clear is Sian.

“I have informed Sian’s family, who are obviously deeply distressed, and I would ask you please to give them time and space to come to terms with what’s happened.

“The public and the media have been a fantastic help in the desperate effort to find Sian over the last few days.

“This has of course been a fast-paced inquiry.

“Having found these bodies, you will appreciate that I am under extreme pressure to undertake certain actions and procedures, and I would ask you to give me some time to enable me to recover these bodies, with the dignity and respect that they deserve.”

He said he was concerned for the family, and the effect this would have on them.

“I want to recover these people and give them the dignity they deserve.”

Police reportedly arrested the suspect outside an Asda supermarket in Swindon.

A green Toyota was also taken away on the back of a trailer.

Meanwhile, police began searching a house in Ashbury Avenue, Swindon.

Neighbours said the man who lived there was a cabbie who drove a green taxi.

A white police tent was erected in the front garden of the semi-detached house.

Specialist dog teams were drafted in to help in the search for Miss O’Callaghan after mobile phone technology pinpointed several areas of interest in the 4,500-acre forest.

Residents in villages about 15 miles to the east of Swindon said a length of road had been sealed off by police.

The stretch, which runs west to east from Broadway, south of Uffington, to Blowingstone Hill, south of Kingston Lisle, has been closed off since the afternoon.
