Cash was withdrawn from Dinah McNicol's account

Dinah McNicol was 18 when she failed to return to her home in Tillingham, Essex, after a trip to a music festival in Hampshire in August 1991.

Essex Police announced last week they were reviewing the investigation into her disappearance.

The force said new information had led them to focus their inquiries on the address in Irvine Drive, Margate.

A police spokeswoman said: "It's vital to stress that this investigation has got nothing to do with the family living at this address."

She added that a "detailed, forensic examination" of the home was taking place.

"We're looking for human remains or anything that links the address to Dinah in any way or any evidence that anything untoward may have happened to her there.

"We expect to be there for two weeks and are digging up the back garden."

Miss McNicol and a friend was last seen in a car with a man after hitching a lift following the festival in Liphook, Hampshire, on 3 August 1991.

Officers believe the pair were picked up by a man in a car, who dropped off Miss McNicol's friend at Junction 8 of the M25 near Reigate, Surrey.

The vehicle and the driver were never traced.

At the time of her disappearance, regular withdrawals of cash were made from her building society account at cash points in Hampshire and Sussex. She had about �2,000 in her account but the withdrawals were out of character.

Miss McNicol's father, Ian McNicol, 68, of Tillingham, said: "Considering the short time the investigation has been reopened, I think this development is absolutely fantastic.

"Hopefully they will be able to put an end to it, either way.

"Ninety-nine percent of me thinks she has been murdered but there's just that 1% that doesn't know.

"I want to die in peace knowing what happened to my daughter."
