£20,000 reward is offered in hunt for missing clubber Sian O'Callaghan
An anonymous donor has offered £20,000 to find missing clubber Sian O'Callaghan.
Details of the reward were issued by Wiltshire Police but the force stressed the person making the gesture wanted no publicity.
Miss O'Callaghan disappeared after leaving Suju nightclub in Swindon at about 2.50am last Saturday.
She has not been seen since she left the Old Town area to walk the half-mile home to the flat she shared with her boyfriend.
Police have launched a massive hunt for the 22-year-old office administrator and are searching woodland at Savernake Forest, near Marlborough, Wiltshire.
Hundreds of volunteers joined police in scouring the woodland.
The office administrator was on a night out with girlfriends at the club before she left alone.
But she never made it home.
Phone masts put her mobile phone in the 4,500-acre forest 32 minutes after leaving the club.
The journey could only have been made by car, said police.
Detective Superintendent Steve Fulcher, who is leading the inquiry, said: “We know that Sian had an LG E900 Optimus mobile phone with her on the night of her disappearance and I'd like to hear from anyone who finds a phone of this description.
“Sian left Suju and walked along the High Street in Old Town and there were a number of vehicles moving through the High Street between 2.55am to 3am.
“We would like to identify the people in those vehicles as possible witnesses.
“I'd also like to hear from anyone who saw any vehicles in or near beauty spots between Swindon and Savernake between 3am and 4am.”
Wiltshire Police have released footage of Miss O'Callaghan alone in the nightclub and hope it will jog revellers' memories.
Police say her disappearance is totally out of character.
Around 400 volunteers joined the search of woodland yesterday for missing clubber Sian O'Callaghan.
Friends of Miss O'Callaghan and her boyfriend Kevin Reape went on organised police searches of Severnake Forest, near Marlborough, Wiltshire.
Local people — many of whom who did not know Miss O'Callaghan — joined in the search as they wanted to |help.
Volunteers were divided into groups and each team went off with a specialist police officer to search the forest.
