A £30,000 reward is being offered for information that helps solve the mystery surrounding the disappearance of Blackpool teenager Paige Chivers.
Paige was just 15 when she was last seen on Ashfield Road, a short distance from the family home in Bispham, on August 23, 2007.
The former Montgomery High school pupil, who would now be 21, went missing just months after her mother Shelia died.
Despite a major police hunt Paige has never been found.
Seven years on, Lancashire’s Police and Crime Commissioner Clive Grunshaw has announced he is to offer a £30,000 reward for any information that leads to a conviction.
Det Supt Andy Webster, who is leading the search for Paige has also renewed his appeals for information.
The Chivers’ family have put out numerous appeals through the media since she vanished after leaving her home on Longford Avenue.
Paige’s picture and description has been shown on television screens in GP and hospital waiting rooms across the country as well as appearing in more than 1,000 high street stores.
But as yet, there have been no more than a few unconfirmed sightings.
In August last year, Paige’s heartbroken father Frank died without learning the fate of his daughter.
Sean Conlon, 44, of no fixed abode has been jailed for life and will have to serve a minimum term of 15 years after he was found guilty of murdering Mr Chivers.
