DETECTIVES were today questioning the estranged husband of missing Highworth mother-of-four Linda Razzell on suspicion of her murder.

Glyn Razzell was arrested and taken to Westlea Police Station after new evidence came to light.

It is the second time police have interviewed Mr Razzell, but the 42-year-old has always insisted he had no part in the disappearance of Linda and has joined appeals for her to get in touch.

Linda, 41, a part-time learning assistant at Swindon College, vanished on Tuesday, March 19.

It is believed that, after dropping off her children in Highworth, she drove her normal route to work in Swindon, parking her red Ford Escort as usual in Alvescot Road, Old Walcot.

There has been no trace of her since, except the recovery of her mobile phone from an alley near where her car was found.

Linda's cousin Julie Westmore, who has travelled from Llanybydder in Wales to help look after Linda's children, said nothing has been heard of Linda since she was last seen.

She and the children, Catherine, 14, Matthew, 12, Emma, nine, and Robin, five, were today at the family home in Pentylands Close, where they were being kept informed about developments.

Detectives have renewed their appeal for people to come forward with any information, no matter how trivial it may appear, concerning Linda.

They released CCTV footage of her on the day before she went missing in the hope it may jog someone's memory.

And they confirmed that she had no spare clothes with her, left her passport behind and has not made any transactions from her bank account. Officers have made a detailed examination of Linda's route to work from Old Walcot to Swindon College, which has included sweeps of Queen's Park in which a team of divers from the Avon and Somerset force searched ponds, lakes and drains.

There was also a reconstruction of Linda's walk to work, via Upham Road and Drove Road, carried out by a member of Swindon police's support staff fitting Linda's description, in which detectives were able to try and gain clues by talking to people whose daily routine could have coincided with the missing mum.

Concern has been voiced from members of Linda's family as well as her boyfriend Gregory Worrall, who made an emotional appeal for her to return.

Mr Razzell, of Meadow Road, Rodbourne, also joined the appeals for her to contact her family.

He said shortly after her appearance that he thought Linda did not wish to be found and could be as far a field as Wales or even France. He added: "We are all getting increasingly concerned but we haven't given up hope."

The Evening Advertiser helped the search by producing posters that have been distributed around the town.

Linda is white, 5ft 2 ins tall, slim, with dark, curly, shoulder length hair which she was wearing in a clip when she was last seen. She has blue eyes and a small scar on the bridge of her nose.

Anyone with information about Linda's whereabouts is asked to contact police on Swindon 528111 or Crimestoppers on 0800 555111.
