A new “aged” photograph has been released of a boy who disappeared when he was 14 years old.
Andrew Gosden walked out of the family home in Doncaster on 14 September 2007.
He was spotted on CCTV arriving on a train at London’s King Cross station but despite an extensive police investigation he has not been seen since.
The image shows how Andrew could look as a 26-year-old and without wearing his glasses.
Det Insp Andy Knowles, who is leading the South Yorkshire Police investigation, said he hoped the new image would “jog someone’s memory”.
“Andrew has now been missing 12 years and his family are understandably desperate for any answers that may help them understand what happened to their loved one,” he said.
“I would also like to take this opportunity to once more appeal to Andrew directly. Andrew, know that you can contact us completely confidentially, let us know you are safe so we can reassure your family that you have come to no harm.”
On the day of his disappearance Andrew skipped school and withdrew just under £200 from his bank account and bought a one-way ticket to London.
His family has commissioned their own searches, including a sonar scan of the River Thames.
A 16-year-old boy has been charged with the murder of a man who was stabbed to death on a north-west London street.
Meshach Williams, 21, died in hospital hours after he was attacked in High Street, Harlesden, on 23 April.
The boy was remanded in custody after appearing at Willesden Magistrates’ Court earlier. He is next due to appear at the Old Bailey on Tuesday.
Three men, aged 19, 18 and 24, have previously been charged in connection with Mr Williams’s death.
They are due to stand trial in November.
A 14-year-old boy accused of a stabbing murder has been remanded to a secure unit.
The teenager, from Barking, appeared at Thames Magistrates’ Court on Saturday morning over the killing of Santino Angelo Dymiter, from Plaistow.
Eighteen-year-old Mr Dymiter was found injured on the afternoon of 26 August by emergency services at Chadd Green, east London.
The judge remanded the 14-year-old to appear at the Old Bailey on Tuesday.
The boy, who cannot be named for legal reasons, is also accused of having a knife in a public place.
